Fix x64/Debug build on MSVS

Also add a CONTRIBUTING.md, that GitHub will link to in the pull request
creation page.

glog: release 0.3.4

migrate to https://github.com/google/glog
use autoconf 2.69 / automake 1.14.1

- ssize_t
Since Windows does not have ssize_t, we need to include BaseTsd.h and
use SSIZE_t instead.

- include algorithm
MSVS 2013 requests developers to include algorithm when they use
std::min.

GTTF: Make stack trace symbolization code recognize more symbols.
One example is __libc_start_main (easy to check), there may be more.

Include the correct elf header on OpenBSD and Android.

For now, we do not remove the declaration of posix_strerror_r,
but we might remove it in future.

- Set -Isrc/windows for mingw
- Check existence of sigaction, pread, and pwrite
- Provide alternative implementation of pread and pwrite
- Eliminate symlink code for OS_WINDOWS
- Don't check /proc/self/fd if the OS isn't linux
- Don't use MSVC specific declarations in port.h for mingw

Casting to (void) was bad because the return value of DCHECK_NOTNULL
cannot be used.

The ABI incompatibility is bad when 

- Build glog without gflags (glog package in most distributions doesn't 
  depend on gflags) 
- Use both glog and gflags

- Remove duplicated code
- Set colorlogtostderr=0 in the unittest

Since FreeBSD do not have gettid system call unlikely to MacOSX, I
modified utilities.h not to use that on FreeBSD:
* FreeBSD lacks gettid syscall.
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/syscalls.master?rev=1.276;content-type=text%2Fplain
* MacOSX gettid == 286.
http://www.opensource.apple.com/source/xnu/xnu-1504.3.12/bsd/kern/syscalls.master
   
As for the fix of stacktrace, we use a different approach.
Even in FreeBSD, package gcc44/gcc46 has unwind.h.
As a result, checking unwind.h should be natural solution.

They are necessary because GLOG_MSVC_* will be expanded at DCHECK



git-svn-id: https://google-glog.googlecode.com/svn/trunk@115 eb4d4688-79bd-11dd-afb4-1d65580434c0

DCHECK* causes "warning C4127: conditional expression is constant".

If compiled with -DWIN32_LEAN_AND_MEAN,
port.h: warning C4005: 'WIN32_LEAN_AND_MEAN': macro redefinition.

On MacOSX,
warning: "_END_GOOGLE_NAMESPACE_" redefined
warning: "_START_GOOGLE_NAMESPACE_" redefined
because config.h is included
 from base/commandlineflags.h:51
 from logging.cc:60
and
 from utilities.h:81
 from logging.cc:32
or so.
