make wait() and friends return reference to self instead of new Future
Summary:
we still make the new Future, but assign it to ourselves. this avoids the following buggy pattern that people might expect to work
```
auto f = ...
f.wait();
// Careful. f.value() was moved out into the new Future, so you may have lost something
someOperationOn(f.value());
// Nope. We already set a callback internally in wait()
f.then(...);

Rework the Future::Core state machine
Summary:
There was a race reading `callback_` in `maybeCallback` and setting `callback_` in `setCallback`. This diff reworks the state machine to make this unpossible. To avoid the explosion of states due to the cross-product of has-interrupt-handler/has-been-interrupted/etc. I introduce a separate lock for setting interrupt handler and interruption, since this is primarily orthogonal. Other attributes (active, for example) are still atomic variables, and while somewhat tied into the state machine logically (e.g. transitioning from Armed to Done only happens when active) they are mostly independent, keeping the state machine simple (and probably faster).
I think it may even be possible to do some things cheaper. In some states, we may not need to protect the writing of `callback_` and `result_`. But we'd need to enforce some ordering so I'm not going to try to tackle that. But that could be some speedup if we can do it cheaply.
Test Plan:
Builds and all existing tests pass.

Convert TransportInfo SSL fields to shared_ptrs
Summary:
We do a lot of copying of TransportInfo in proxygen, and in most cases
the SSL structs don't change after connection establishment. We could
cut down on memory usage by sharing these huge strings. This is
especially true with SPDY where all streams belonging to a session could
share these fields.

Add additional instantiations in Instantiations.cpp
Summary:
Histogram::getPercentileBucketIdx() and getPercentileEstimate() are
implemented using template methods of HistogramBuckets.
This updates Instantiations.cpp to also instantiate the versions of
these template methods that are required by Histogram<int64_t>. Without
this, anyone using these methods was required to also include
Histogram-defs.h, or otherwise they may get link errors. This makes it
so they no longer need to include Histogram-defs.h
The C++ syntax required is pretty horrendous. We could potentially
avoid this by refactoring the code so that these methods are no longer
templates (and require that the Bucket class provide methods for this
purpose). At the moment adding instantiations seems simpler, and
doesn't change any public APIs.

Summary:
Introduce ProgressableExecutor, which is an Executor that can be driven somehow. Examples include EventBase and ManualExecutor
Then introduce Future<T>::getVia(ProgressableExecutor*) and Future<T>::waitVia(ProgressableExecutor*) that drive the given executor until the Future is complete, with the usual semantics of get and wait respectively
This is a really common pattern in tests and you can see in the various changes to other projects lends sopme nice redness and cleanliness
Some notes:
1. I don't like ProgressableExecutor::makeProgress() that much. Too verbose. Maybe DrivableExecutor::drive()? Something else? Thoughts?
2. I still need to integrate this with some stuff in Zeus (SessionFuture) and Zookeeper (ZookeeperFuture) but I'm going to do that in a separate diff because it's going to be a little more intrusive

codecs
Summary:
Start of codec framework. Copied the frame based codecs almost exactly from netty, but made to fit our pipeline management.
BytesToMessageCodec is slightly different: Netty preprocesses all the available data to a List<Message>, while this codec a) Only does one message at a time to avoid queueing issues, and b) doesn't template the message type, and just passes an IOBuf
I'm fighting the type system to get the pipelines to play nice to each other: I'd rather template the message type, but it prevents stacking outgoing handlers on top of it, since you ahve to specify both the input/output type for each handler, even if you only care about the output type. Suggestions to fix? Netty gets around this by lots of dynamic casting to Object type, but we can't do that in C++ since we don't have a base object type

Try to fix IdleTime unit test
Summary:
IdleTime unit test has been failing randomly (#
5996886). The
event base loop calculates an exponentially moving average of loop busy
time in each loop. In the test, the busy time is initialized to 5900 and
each loop runs more than 8000 us. In normal case decaying of the
previous loop busy time will take 6 loops to move this average to >6000.
But if the test is running on a heavily loaded machine the busy+idle time
a loop is longer than it should be, causing the decaying happen faster.
This diff skips this test if this happens.

It won't affect anything if running on my devserver. It only
helps on a heavily loaded contbuild host.

folly: Bits: restore type of bitOffset_ to shorter "unsigned int"
Summary:
My initial change to avoid the -Wsign-compare error neglected
the fact that the difference of two unsigned types is also
unsigned. That broke some unicorn tests, as seen in
D1776343,
which worked around the problem by changing the type of
bitOffset_ like this: s/unsigned int/size_t.
The real problem lay in the distance_to function, which computed
the signed difference of two bitOffset_ values.
To work properly with the narrower unsigned type,
we could either first widen each operand to ssize_t
before computing their parenthesized difference, or
(as Philip suggested and I prefer), just drop the
parentheses and let the signedness of the preceding
operands ensure that each successive intermediate
result is also signed.
Test Plan:
Choose one of the failing tests, and ensure it now passes:
fbconfig -r unicorn/diskindex4/test:doc_map_test
fbmake runtests
Also run all unicorn tests, for good measure (still waiting):
fbconfig -r unicorn && fbmake runtests

MPMCQueue.h: fix a bug introduced while accommodating -Wsign-compare
Summary:
* folly/MPMCQueue.h (waitForTurn): My changes to accommodate
-Wsign-compare introduced a bug that could cause lots of wasted CPU.
(See @scottf's comments on the blamed patch.)
Subtraction involving an unsigned type will always yield an unsigned
result, and there was at least this one instance where the result
would sometimes have to be a small negative number. Instead, we'd
get approximately UINT32_MAX. The fix is to explicitly cast the
difference to a signed type.
Test Plan:
Run this and note there is no error:
(this ensures it remains -Wsign-compare-clean with gcc-4.9)
fbconfig --platform-all=gcc-4.9-glibc-2.20 tao/server && fbmake dbgo
Before this change, running the mpmc_queue_test test would get
timeout errors ~8 in 100 runs. Confirm that with this patch, now
there is no type of failure. I.e., run these commands and ensure
the grep prints nothing:
fbconfig folly/test:mpmc_queue_test
for i in $(seq 100); do fbmake runtests_dbgo >& makerr-$i; done
grep -E '(TIMEOUT|FATAL|FAIL).* [1-9]' makerr-*

folly: fix many -Wsign-compare warning/errors reported by gcc-4.9

With the upgrade to gcc-4.9 fbcode's default is to enable
-Wsign-compare by default. That exposes nontrivial technical debt.
This is part of that clean-up. Some of these changes fix the problem
where there's an "int" for-loop index, yet an unsigned limit.
The fix is to use an unsigned type when the limit is also unsigned.
I usually choose size_t because of the general recommendation (when
writing portable code) to avoid size-tied types like uint32_t and
uint64_t unless you have a very good reason to require them.

folly/FBString.h: avoid -Wsign-compare error
Summary:
* folly/FBString.h (operator>>): Since istream.width() is signed,
handle the case of a negative width. This avoids risk that "n"
will be less than 0 when compared against unsigned "extracted".
However, to suppress the following warning, we must also explicitly
convert "n" to size_t before comparing:
folly/FBString.h:2326:22: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
Test Plan:
Run this and note there are fewer errors than before:
fbconfig --platform-all=gcc-4.9-glibc-2.20 -r folly && fbmake dbgo

exception_ptr -> exception_wrapper migration
Summary:
integrate exception_wrapper everywhere, and deprecate public methods that take ptrs directly to discourage their use
note that this will break for throwing non-exceptions, which is probably fine
this change opens the door to interesting optimizations for those interested, e.g. Future::then<Exn1, Exn2>(/* func throwing Exn1 and Exn2 */) that autowraps the given types into the resultant future
new benchmark:
```
throwAndCatch 23.69us 42.21K
throwAndCatchWrapped 119.53% 19.82us 50.45K
throwWrappedAndCatchWrapped 350.16% 6.77us 147.80K
```
Test Plan: existing unit tests, suspected potential perf wins confirmed by benchmark, will wait for windtunnel to see other wins/regressions
