The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

Like the last patch, the motivation is to remove a GetVersionEx() call which
triggers deprecation warnings.
Because Windows XP SP2 is the earliest Windows version we support, two of the
existing uses of GetWinVersion() could be removed, because they were checking
for XP or earlier. One other Vista check could be replaced with
mozilla::IsVistaOrLater().
The motivation here is to remove the GetVersionEx() calls in the
Windows-specific code, because that function is deprecated and causes warnings.
The non-Windows versions come along for the ride.
Two parts.
- Most of the common stuff goes into the new libeventcommon.mozbuild file.
- A little bit of common bsd/linux stuff factored out in
ipc/chromium/moz.build.
I originally tried putting it in ipc/chromium/src/third_party/libevent/, but
that directory already has a Makefile.in file, which caused problems, so I
moved it down one directory.
We get the following warnings with clang.
> ipc/chromium/src/base/time_posix.cc:103:57: error: overflow in expression; result is 0 with type 'long' [-Werror,-Winteger-overflow]
> ipc/chromium/src/base/time_posix.cc:106:58: error: overflow in expression; result is -1000 with type 'long' [-Werror,-Winteger-overflow]
This is a genuine bug. The upstream code in Chromium has changed (commit
2a278516943eee02e0206506a4b907fc0b55f27b) and this patch changes our code to be
similar. I did tests and confirmed that instead of getting 0 or -1 for
|milliseconds|, we now get -2147483648000 or 2147483647999, which is much
better.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
