Nick Mathewson 195aa2f5f7 annotate_ifdef_directives: generate paren-balanced expressions
This algorithm is not fully general, but it strikes a balance
between efficiency, simplicity, and correctness.

Nick Mathewson 21cc9d13f3 annotate_ifdef_directives: clarify situation with newlines
Our line limit is 80 characters, assuming that there is a single
terminating newline character that counts towards the limit.  On
Windows, this might go as high as 81 characters, if we count CRLF as
two characters.

Nick Mathewson 65e63e7461 annotate_ifdef_directives: remove some cases of double negation
This change should reduce the number of cases where we say
"/* !(!defined(foo)) */" .

This only does cases where we can use a regex to make sure that the
simplification is guaranteed to be correct.  Full boolean
simplification would require this script to parse C, and nobody
wants that.

teor d1eab05834 lock: Avoid some undefined behaviour when freeing mutexes.

teor 749c2e1761 log: explain why it is safe to leave the log mutex initialized
The log mutex is dynamically initialized, guarded by log_mutex_initialized.
We don't want to destroy it, because after it is destroyed, we won't see
any more logs.

If tor is re-initialized, log_mutex_initialized will still be 1. So we
won't trigger any undefined behaviour by trying to re-initialize the
log mutex.

teor 315f14c709 backtrace: avoid undefined behaviour on re-initialisation
cb_buf_mutex is statically initialised, so we can not destroy it when
we are shutting down the err subsystem. If we destroy it, and then
re-initialise tor, all our backtraces will fail.

teor 1ad1e84b17 log: Move SEVERITY_MASK_IDX() to log.h
Move SEVERITY_MASK_IDX() to log.h private/unit tests section, so that
we can use it in log.c, the unit tests, and the fuzzers.

(The test and fuzzer code changes are in a subsequent commit.)

I started this repository a while ago to work on documentation for
Tor's internals.  It needs substantial revision, but first, let's
get it copied into Tor's repository.

These files are copied, "warts and all", from the tor-guts.git repo,
commit de1e34259178b09861c0dea319c760fa80d0099a.

Frequently, when a patch fails, it has failures in several files.
Using the "-k" flag will let us learn all the compilation errors,
not just the first one that the compiler hits.

Based on a patch by rl1987.

Daniel Pinto 15490816da Fix bug when %including folder with comment only files. #31408
When processing a %included folder, a bug caused the pointer to
the last element of the options list to be set to NULL when
processing a file with only comments or whitepace. This could
cause options from other files on the same folder to be
discarded depending on the lines after the affected %include.
