We already enable -fstrict-aliasing when gcc >= 4.6.0 but let's enable it for
gcc < 4.5.0 as well. The aliasing bugs that we ran into in the past are all
particular to the 4.5.x releases.
* compile with -DOPENSSL_NO_SOCK and -DOPENSSL_NO_DGRAM, we don't need it
* compile with -DOPENSSL_NO_GOST and -DOPENSSL_NO_HW_PADLOCK, works around the
brain dead linker on solaris and maybe others
* compile with -DTERMIOS, OS X doesn't have <termio.h>
* compile with -D__EXTENSIONS__ on solaris, makes siginfo_t available
* compile without -ansi on linux, it hides a number of POSIX declarations
(sigaction, NI_MAXHOST, etc.)
* fixes#2110
* includes V8 postmortem metadata in Solaris builds
* adds GYP support for DTrace probes and ustack helper
* ustack helper derives constants dynamically from libv8_base.a
* build with DTrace support by default on SunOS
A compiler bug in older versions of gcc makes it do unsafe optimizations at -O1
and higher. This manifested itself with (at least) gcc 4.5.2 on SmartOS because
it made V8 hang in a busy loop.

Fixes a struct stat size mismatch on 64 bits machines that made Node crash with
a EXC_BAD_ACCESS on startup.
Fixes#2061 for gyp builds. Solution proposed by Paddy Byers.
Hoist common settings into common.gypi.
Restrict v8's common.gypi to v8 projects.
Ensure v8 doesn't use /MP in debug builds.
Add basic settings for other platforms.
Make uv import common.gypi properly.
Remove LTCG warning.
