5d147d8527 Add a new flag to check_private_dir to make it _not_ change permissions
We'll need this for checking permissions on the directories that hold
control sockets: if somebody says "ControlSocket ~/foo", it would be
pretty rude to do a chmod 700 on their homedir.

Conflicts throughout.  All resolved in favor of taking HEAD and
adding tor_mem* or fast_mem* ops as appropriate.

59f9097d5c Hand-conversion and audit phase of memcmp transition
Here I looked at the results of the automated conversion and cleaned
them up as follows:

   If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
   changed it to a fast_memcmp or fast_memeq.

   Otherwise if there was a tor_memcmp that could turn into a
   tor_memneq or tor_memeq, I converted it.

This wants close attention.

[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.

418e6caeeb New function to load windows system libraries
This function uses GetSystemDirectory() to make sure we load the version
of the library from c:\windows\system32 (or local equivalent) rather than
whatever version lives in the cwd.

235f1e1a96 Refactor out the 'find string at start of any line' logic.
We do this in too many places throughout the code; it's time to start
clamping down.

Also, refactor Karsten's patch to use strchr-then-strndup, rather than
malloc-then-strlcpy-then-strchr-then-clear.

00b37f071d Revise parsing of time and memory units to handle spaces.
When we added support for fractional units (like 1.5 MB) I broke
support for giving units with no space (like 2MB).  This patch should
fix that.  It also adds a propoer tor_parse_double().

Fix for bug 1076.  Bugfix on 0.2.2.1-alpha.

7b716878cb Fix dirreq and cell stats on 32-bit architectures.
When determining how long directory requests take or how long cells spend
in queues, we were comparing timestamps on microsecond detail only to
convert results to second or millisecond detail later on. But on 32-bit
architectures this means that 2^31 microseconds only cover time
differences of up to 36 minutes. Instead, compare timestamps on
millisecond detail.

uint64_t.

6ac3a8b0cd Command-line option to dump SHA1 digests of all source files.
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with.  We support both 'sha1sum' and
'openssl sha1'.  If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1.  If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.

26d83fc04c Add a simple locale-independent no-surprises sscanf replacement.
tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing.  We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

bf80e2df3f Replace calls to time(NULL) that occur on the order of once per read, one per write, or once per cell with calls to a function that looks at a cached value of time. This is tricksy to benchmark, since it will only help on systems where time() is a syscall and syscalls are relatively slow.
