2420c8c936 test: Avoid a map_anon_nofork test failure on SunOS
This test failure happened due to a signed/unsigned integer
comparison.

This bug occurred on SunOS, it may also occur on other systems that
use signed char as the default. (And cast 1-byte integer constants
to an unsigned integer.)

Fixes bug 31897; bugfix on 0.4.1.1-alpha.

fc1134e3e5 annotate_ifdef_directives: test edge-case of 80-char line
An 80-character line (79 characters if you don't count the newline)
should not be truncated, and should not have a "..." insterted.

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.

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.

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.

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.

469051f650 Copy architectural documentation from tor-guts.git repository
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.
