Build on Ubuntu 10.04 64-bit was failing:
util.c: In function ‘parse_http_time’:
util.c:1370: error: not protecting function: no buffer at least 8 bytes long
We don't want to lose -Werror, and we don't care too much about the
added overhead of protecting even small buffers, so let's simply turn on
SSP for all buffers.
Thanks to Jacob Appelbaum for the pointer and SwissTorExit for the
original report.

This patch adds support for two new configure options:
'--enable-gcc-hardening'
This sets CFLAGS to include:
"-D_FORTIFY_SOURCE=2 -fstack-protector-all"
"-fwrapv -fPIE -Wstack-protector -Wformat -Wformat-security"
"-Wpointer-sign"
It sets LDFLAGS to include:
"-pie"
'--enable-linker-hardening'
This sets LDFLAGS to include:
" -z relro -z now"
The main changes are to explain how we use git branches, how we use
changes files, and what should go into a patch. Putting these in
HACKING means that we shouldn't need to constantly refer to the or-dev
emails where we explain this stuff.
what's happening here is that we're fetching certs for obsolete
authorities -- probably legacy signers in this case. but try to
remain general in the log message.
It's natural for the definition of bandwidth_rule_t to be with the functions
that actually care about its values. Unfortunately, this means declaring
bandwidth_rate_rule_to_string() out of sequence. Someday we'll just rename
reasons.c to strings.c, and put it at the end of or.h, and this will all be
better.
1) mingw doesn't have _vscprintf(); mingw instead has a working snprintf.
2) windows compilers that _do_ have a working _vscprintf spell it so; they do
not spell it _vcsprintf().
Works like the --enable-static-openssl/libevent options. Requires
--with-zlib-dir to be set. Note that other dependencies might still
pull in a dynamicly linked zlib, if you don't link them in statically
too.
