Original commit message:
heap: make array buffer maps disjoint
Remove intersection from the `std::map`s representing current live
ArrayBuffers. While being simpler to understand, it poses
significant performance issue for the active ArrayBuffer users (like
node.js).
Store buffers separately, and process them together during
mark-sweep phase.
The results of benchmarks are:
$ ./node-slow bench && ./node-fast bench
4997.4 ns/op
4685.7 ns/op
NOTE: `fast` - was a patched node.js, `slow` - unpatched node.js
with vanilla v8.

It was pointed out by Zhou Ran that the Windows XP implementation of
uv_rwlock_rdlock() and friends may unlock the inner write mutex on a
different thread than the one that locked it, resulting in undefined
behavior.
The only place that uses rwlocks is the crypto module. Make that use
normal (simple) mutexes instead.
OpenSSL's critical sections are generally very short, with exclusive
access outnumbering shared access by a factor of three or more, so
it's not as if using rwlocks gives a decisive performance advantage.

cpplint uses the top-level .git directory to determine what the root is
for #include guards. If it doesn't find a .git directory, it walks up
all the way to the system root and subsequently complains that guards
must be written as HOME_USER_SRC_NODE_SRC_FILENAME_H_.
This commit replaces the .git-based path munging with a fixed root path
relative to the location of the cpplint script, making it possible to
successfully run `make test` from an extracted tarball.

This commit addresses most of the review comments in
https://github.com/nodejs/node/pull/2540, which are kept in this
separate commit so as to better preserve the prior two patches as they
landed in 0.12.
This commit:
- Fixes a bug with unrefActive timers and disposed domains.
- Fixes a bug with unrolling an unrefActive timer from another.
- Adds a test for both above bugs.
- Improves check logic, making it stricter, simpler, or both.
- Optimizes nicer with a smaller, separate function for the try/catch.

Before this change, _unrefActive would keep the unrefList sorted when
adding a new timer.
Because _unrefActive is called extremely frequently, this linear scan
(O(n) at worse) would make _unrefActive show high in the list of
contributors when profiling CPU usage.
This commit changes _unrefActive so that it doesn't try to keep the
unrefList sorted. The insertion thus happens in constant time.
However, when a timer expires, unrefTimeout has to go through the whole
unrefList because it's not ordered anymore.
It is usually not large enough to have a significant impact on
performance because:
- Most of the time, the timers will be removed before unrefTimeout is
called because their users (sockets mainly) cancel them when an I/O
operation takes place.
- If they're not, it means that some I/O took a long time to happen, and
the initiator of subsequents I/O operations that would add more timers
has to wait for them to complete.
With this change, _unrefActive does not show as a significant
contributor in CPU profiling reports anymore.
