note was copied from google-perftools's notice (google-perftools/INSTALL).  I
modified the notice because the situation around stacktracer is a bit different
between glog and perftools.  Perftool's tcmalloc hooks malloc and its
stacktracer must not call malloc.  In glog, stacktracer with malloc can be an
issue only when users use InstallFailureSignalHandler() and a signal is raised
inside malloc.

Since we introduced the API to set signal handler and print a
stacktrace, we should avoid glibc's backtrace, which may call malloc.
Basically, we choose the way to produce a stacktrace as same as
perftools.

Also, I removed GetStackFrames, which is not used and not implemented
with glibc.

The original way (ls && tail -n 1) could not handle version numbers which have patch level proprely (e.g., 0.1.1.tar.gz is considered less than 0.1.tar.gz since ls command orders files lexicographically).

Add InstallFailureSignalHandler().  The function installs a signal handler that will dump useful information when the program crashes on certain signals such as SIGSEGV.

will dump useful information when the program crashes on certain signals such
as SIGSEGV.
Also, changed the version of autoconf (2.59 => 2.61).

gflags isn't initialized when REGISTER_MODULE_INITIALIZER is invoked,
we couldn't initialize vmodule_list properly. Modified to call
VLOG2Initializer in the first call of InitVLOG3__.

has execinfo.h (e.g., MacOSX 10.5). Though dladdr may not be async
signal safe, it's OK since glog's stacktrace doesn't depend on signals.
