Remove autogen.sh, since you can just use autoreconf instead.

Ran autoreconf and fixed a couple of issues that popped up in
configure.ac and m4/ac_rwlock.m4.  This updates the configuration
files to automake/aclocal 1.11.1 (from 1.10.1) and to autoconf 2.65
(from 2.61).

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.

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

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.
