log: When initialising log domain masks, only set known log domains 
And add a runtime test that checks for unknown domains and flags.

Fixes bug 31854; bugfix on 0.2.1.1-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.
