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.
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.
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.

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.
Part of 31736, but committed in this branch to avoid merge conflicts.
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.)
Preparation for bug 31334.
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.
Part of 31819.
- The function `decrypt_desc_layer` has a cleaner interface.
