Pipeline OutputBufferingHandler
Summary: Part 2 of pipeline. Use OutputBufferingHandler, which is exactly the same output buffering thrift does currently.
Test Plan:
A couple canaries, unittests.
Specific issues of previous pipeline diffs I think are fixed already and should be fine with this one:
* Previously there were missing DestructorGuards. I don't think anything in OutputBUfferHandler needs a DG
* previously broke http GET handling. There is a unittest for it now.

GlobalExecutor.h include Executor.h and IOExecutor.h
Summary: We were forward-declaring `Executor` and `IOExecutor` for great compilation speed. However, this leaves users of this header to include at least one of those headers in their cpp file to actually use it, and that's kind of annoying. `Executor` and `IOExecutor` are not templated and are quite small, so it seems like the compilation speed benefit is minimal compared to the convenience factor, so this diff just includes the two headers. (Probably including `Executor.h` is redundant since `IOExecutor.h` probably includes it, but for completeness and explicitness, and in case `IOExecutor` also just forward-declares `Executor` now or in the future.)

(Wangle) Allocate lambda space inside Core instead of inside std::function
Summary:
Taking this trick that is used in the fibers library. We can keep 64
bytes of space inside `Core` to allocate the callback lambda into,
instead of having `std::function` do another `malloc`. This seems to
greatly improve the synthethic benchmark, and hopefully production
workloads, too, by reducing the number of mallocs.
64 bytes were picked because it fits all the lambdas in the futures
tests. We might want to adjust this based on production data...?

MPMCQueue - FPE to invalid_argument for 0 capacity
Summary:
If an MPMCQueue was initialized with an explicit zero capacity, it would
try to compute stride for zero and trigger SIGFPE which pretty fatally
killed the process -- but in a way that required gdb to figure out the
root cause.
This replaces that with a std::invalid_argument exception, which
includes a description of the problem and should make fixing this user
error much faster.

GTEST unit test added to verify behaviour; if this didn't work it would
SIGFPE and abort the test script, which is probably a good indicator
that something went wrong. :)

Add CaptureFD for log testing (and some glog patterns)
Summary:
Without a gadget like this, it's really hard to test logging output. With it, it's really easy. I found about 50 callsites to the various functions across several projects, so folly seems appropriate.
PS The patterns are functions for two reasons:
- Static variables are a pain.
- This leaves the option of adding an optional argument, so you can grep for a particular kind of error string.

TemporaryFile and TemporaryDirectory
Summary:
TemporaryFile, TemporaryDirectory, and ChangeToTempDir should all be moveable

Udp Acceptor
Summary:
major changes:
1) ServerSocketFactory and AsyncSocketBase to abstract the differences between UDP and TCP async socket. Could possibly push some of this to the sockets themselves eventually
2) pipeline() is a pipeline between accept/receive of a UDP message, and before sending it to workers. Default impl for TCP is to fan out to worker threads. This is the same as Netty. Since we don't know if the data is a TCP socket or a UDP message, it's a void*, which sucks (netty uses Object msg, so it isn't any different).
Test Plan: Added lots of new tests. Doesn't test any data passing yet though, just connects/simple receipt of UDP message.

This code is only used in a test so far.
Basically it looks like Pipeline has some dependency issues - any addBack() pipelines have to be deleted *after* the main pipeline is destroyed. Ideally if the pipeline is already closed, the destruction order wouldn't matter. There is currently no removeBack() call either. This is a quick fix for the test to just delete stuff in the right order, we can discuss a better solution when @jsedgwick returns

SharedMutex - a small fast scalable reader-writer lock
Summary:
SharedMutex is a reader-writer lock. It is small, very fast, scalable
on multi-core, and suitable for use when readers or writers may block.
Unlike most other reader-writer locks, its throughput with concurrent
readers scales linearly; it is able to acquire and release the lock
in shared mode without cache line ping-ponging. It is suitable for a
wide range of lock hold times because it starts with spinning, proceeds
to using sched_yield with a preemption heuristic, and then waits using
futex and precise wakeups.
SharedMutex provides all of the methods of folly::RWSpinLock,
boost::shared_mutex, boost::upgrade_mutex, and C++14's
std::shared_timed_mutex. All operations that can block are available in
try, try-for, and try-until (system_clock or steady_clock) versions.
Both reader-priority and writer-priority versions are provided.
Writer-priority is the default at the moment.
In my tests SharedMutex is as good or better than the other reader-writer
locks in use at Facebook for almost all use cases, sometimes by a wide
margin. (If it is rare that there are actually concurrent readers
then RWSpinLock can be a few nanoseconds faster.) I compared it to
folly::RWSpinLock, folly::RWTicketSpinLock64, boost::shared_mutex,
pthread_rwlock_t, and an internal RWLock that uses spinlocks to guard
its state and pthread_mutex_t+pthread_cont_t to perform blocking.
(The other ReadWriteMutex-s I found use pthread_rwlock_t underneath.)
It is generally as good or better than the rest when evaluating size,
speed, scalability, or latency outliers. In the corner cases where
it is not the fastest (such as single-threaded use or heavy write
contention) it is never very much worse than the best. See the bottom
of SharedMutexTest.cpp for lots of microbenchmark results.
Test Plan:
1. new unit tests
2. new microbenchmarks included here
3. uncommitted microbenchmark from bmaurer's RWSleepLock
4. replace admarket's RWSpinLock and RWLock with SharedMutex, observe
neutral adindexer perf in canary
5. replace multifeed's thrift ReadWriteLock with SharedMutex, observe
neutral perf in canary

Add JSON Schema Validator
Summary:
This is a validator for JSON schema (http://json-schema.org/) that works on
folly::dynamic. Apparently there are no good open source ones for C++,
especially not if you want to use folly::dynamic. I am going to use this to
validate JSON configs.
It supports basically everything from the standard, except for fetching schemas
via http, and using id refs. It supports enough to check schemas against the
metaschema.
Currently you can define a schema that will crash on validation, if it's
infinitely self-recursive. See the unit test case that reproduces this.
Fixing this seems hard though, so I didn't bother. It would also probably
be slower for normal usage.
