If we manually remove fallbacks in C by adding '/*' and '*/' on separate
lines, stem still parses them as being present, because it only looks at
the start of a line.
Add a comment to this effect in the generated source code.
Remove a fallback that changed its fingerprint after it was listed
This happened after to a software update:
https://lists.torproject.org/pipermail/tor-relays/2016-June/009473.html
Remove a fallback that changed IPv4 address
Remove two fallbacks that were slow to deliver consensuses,
we can't guarantee they'll be fast in future.
Blacklist all these fallbacks until operators confirm they're stable.
Make sure to memset(0) the destination buffer so we don't leave any
uninitialized data.

This hack provides a way to make sure we can see coverage from
test-switch-id. If you set OVERRIDE_GCDA_PERMISSIONS_HACK, we
temporarily make the .gcda files mode 0666 before we run the
test scripts, and then we set them to 0644 again afterwards.
That's necessary because the test_switch_id.sh script does a
setuid() to 'nobody' part way through, and drops the ability to
change its mind back.
Slow system can sometime take more than 10 seconds to reach the test
callsite resulting in the unit test failing when using time in the future or
in the past.

base16_decodes() now returns the number of decoded bytes. It's interface
changes from returning a "int" to a "ssize_t". Every callsite now checks the
returned value.

realloc()ing a thing in order to try to save memory on it just
doesn't make sense with today's allocators. Instead, let's use the
fact that whenever we decompress something, either it isn't too big,
or we chop it up, or we reallocate it.
zlib 1.2 came out in 2003; earlier versions should be dead by now.
Our workaround code was only preventing us from using the gzip
encoding (if we decide to do so), and having some dead code linger
around in torgzip.c
