The strcmp_len() function was somewhat misconceived, since we're
only using it to test whether a length+extent string is equal to a
NUL-terminated string or not. By simplifying it and making it
inlined, we should be able to make it a little faster.
(It *does* show up in profiles.)
Closes ticket 28856.
The old implementation did some funky out-of-order lexing, and
tended to parse every port twice if the %d-%d pattern didn't match.
Closes ticket 28853.
I believe we originally added this for "just in case" safety, but it
isn't actually needed -- we never copy uninitialized stack here.
What's more, this one memset is showing up on our startup profiles,
so we ought to remove it.
Closes ticket 28852.
The point of this function is to make sure that the ed25519-based
implementation of curve25519_basepoint() actually works when we
start tor, and use the regular fallback implementation if it
doesn't. But it accounts for 9% of our startup time in the case
when we have directory information, and I think it's safe to make
the test shorter. After all, it has yet to find any actual bugs in
curved25519_scalarmult_basepoint_donna() on any platforms.
Closes ticket 28838.
When the clock jumps, and we have a record of last user activity,
adjust that record. This way if I'm inactive for 10 minutes and
then the laptop is sleeping for an hour, I'll still count as having
been inactive for 10 minutes.
Previously, we treat every jump as if it were activity, which is
ridiculous, and would prevent a Tor instance with a jumpy clock from
ever going dormant.
encoding and decoding.
There are bunches of places where we don't want to invest in a full
fuzzer, but we would like to make sure that some string operation
can handle all its possible inputs. This fuzzer uses the first byte
of its input to decide what to do with the rest of the input. Right
now, all the possibilities are decoding a string, and seeing whether
it is decodeable. If it is, we try to re-encode it and do the whole
thing again, to make sure we get the same result.
This turned up a lot of bugs in the key-value parser, and I think it
will help in other cases too.

Appveyor images are named after the Visual Studio version they contain.
But we compile using MinGW, not Visual Studio.
We use these images because they have different Windows versions.
Closes bug 28826.
Add the bootstrap tag name to the log messages, so people
troubleshooting connection problems can look up a symbol instead of a
number. Closes ticket 28731.
Merge Phoul's two lists into teor's list.
Replace the 150 fallbacks originally introduced in Tor 0.3.3.1-alpha in
January 2018 (of which ~115 were still functional), with a list of
157 fallbacks (92 new, 65 existing, 85 removed) generated in
December 2018.
