fcebc8da95 Rename socks5 error code setting function again
I'd prefer not to use the name "send" for any function that doesn't
really send things.

41a8930fa1 scan-build: check impossible null-pointer case in buffers.c
When maintaining buffer freelists, we don't skip more than there
are, so (*chp) can't be null to begin with.  scan-build has no way
to know that.

833d027778 Monotonize the OOM-killer data timers
In a couple of places, to implement the OOM-circuit-killer defense
against sniper attacks, we have counters to remember the age of
cells or data chunks.  These timers were based on wall clock time,
which can move backwards, thus giving roll-over results for our age
calculation.  This commit creates a low-budget monotonic time, based
on ratcheting gettimeofday(), so that even in the event of a time
rollback, we don't do anything _really_ stupid.

A future version of Tor should update this function to do something
even less stupid here, like employ clock_gettime() or its kin.

eabcab2b7c Count freed buffer bytes from buffers when oom-killing circuits.
Also, aggressively clear the buffers to try to make their bytes go
away fast rather than waiting for the close-marked-connection code
to get 'em.

a3e0a87d95 Completely refactor how FILENAME_PRIVATE works
We previously used FILENAME_PRIVATE identifiers mostly for
identifiers exposed only to the unit tests... but also for
identifiers exposed to the benchmarker, and sometimes for
identifiers exposed to a similar module, and occasionally for no
really good reason at all.

Now, we use FILENAME_PRIVATE identifiers for identifiers shared by
Tor and the unit tests.  They should be defined static when we
aren't building the unit test, and globally visible otherwise. (The
STATIC macro will keep us honest here.)

For identifiers used only by the unit tests and never by Tor at all,
on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS.

This is not the motivating use case for the split test/non-test
build system; it's just a test example to see how it works, and to
take a chance to clean up the code a little.

00e2310f12 Don't run off the end of the array-of-freelists
This is a fix for bug 8844, where eugenis correctly notes that there's
a sentinel value at the end of the list-of-freelists that's never
actually checked.  It's a bug since the first version of the chunked
buffer code back in 0.2.0.16-alpha.

This would probably be a crash bug if it ever happens, but nobody's
ever reported something like this, so I'm unsure whether it can occur.
It would require write_to_buf, write_to_buf_zlib, read_to_buf, or
read_to_buf_tls to get an input size of more than 32K.  Still, it's a
good idea to fix this kind of thing!

49dd5ef3a3 Add and use and unlikely-to-be-eliminated memwipe()
Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope.  I've gone with the safest
possible replacement, which might be a bit slow.  I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.

Fixes bug 7352.

Also, try to resolve some doxygen issues.  First, define a magic
"This is doxygen!" macro so that we take the correct branch in
various #if/#else/#endifs in order to get the right documentation.
Second, add in a few grouping @{ and @} entries in order to get some
variables and fields to get grouped together.

e0e4b84757 Add a check_no_tls_errors() to read_to_buf_tls
Fixes bug #4528 "read_to_buf_tls(): Inconsistency in code".

This check was added back in 0.1.0.3-rc, but somehow we forgot to
leave it in when we refactored read_to_buf_tls in 0.1.0.5-rc.
