Prop298 says that family entries should be formatted with
$hexids in uppercase, nicknames in lower case, $hexid~names
truncated, and everything sorted lexically. These changes implement
that ordering for nodefamily.c.
We don't _strictly speaking_ need to nodefamily.c formatting use
this for prop298 microdesc generation, but it seems silly to have
two separate canonicalization algorithms.
This representation is meant to save memory in microdescriptors --
we can't use it in routerinfo_t yet, since those families need to be
encoded losslessly for directory voting to work.
This representation saves memory in three ways:
1. It uses only one allocation per family. (The old way used a
smartlist (2 allocs) plus one strdup per entry.)
2. It stores identity digests in binary, not hex.
3. It keeps families in a canonical format, memoizes, and
reference-counts them.
Part of #27359.
The previous "ALL" role was the OR of a bunch of other roles,
which is a mistake: it's better if "ALL" means "all".
The "NET_PARTICIPANT" role refers to the anything that is actively
building circuits, downloading directory information, and
participating in the Tor network. For now, it is set to
!net_is_disabled(), but we're going to use it to implement a new
"extra dormant mode".
Closes ticket 28336.
If tor terminates due to SIGNAL HALT before test_rebind.py calls
tor_process.terminate(), an OSError 3 (no such process) is thrown.
Fixes part of bug 27968 on 0.3.5.1-alpha.
With the new refresh_service_descriptor() function we had both
refresh_service_descriptor() and update_service_descriptor() which is basically
the same thing.
This commit renames update_service_descriptor() to
update_service_descriptor_intro_points() to make it clear it's not a generic
refresh and it's only about intro points.

Treat backtrace test failures as expected on NetBSD, OpenBSD, and
macOS/Darwin, until we solve bug 17808.
(FreeBSD failures have been treated as expected since 18204 in 0.2.8.)
Fixes bug 27948; bugfix on 0.2.5.2-alpha.
Occasionally, key pinning doesn't catch a relay that shares an ed25519
ID with another relay. Log the identity fingerprints and the shared
ed25519 ID when this happens, instead of making a BUG() warning.
Fixes bug 27800; bugfix on 0.3.2.1-alpha.
It looks to be the case that Rust's standard allocator, jemalloc, is
incompatible with sanitizers. The incompatibility, for whatever reason,
seems to cause segfaults at runtime when jemalloc is linked with
sanitizers.
Without actually trying to figure out what's going on here this commit
instead takes the hammer of "let's remove jemalloc when testing". The
`tor_allocate` crate now by default switches to the system allocator
(eventually this will want to be the tor allocator). Most crates then
link to `tor_allocate` ot pick this up, but the `smartlist` crate had to
manually switch to the system allocator in testing and the `external`
crate had to be sure to link to `tor_allocate`.
The final gotcha here is that this patch also switches to
unconditionally passing `--target` to Cargo. For weird and arcane
reasons passing `--target` with the host target of the compiler (which
Cargo otherwise uses as the default) is different than not passing
`--target` at all. This ensure that our custom `RUSTFLAGS` with
sanitizer options doesn't make its way into build scripts, just the
final testing artifacts.
This is no longer necessary with upstream rust-lang/rust changes as well
as some local tweaks. Namely:
* The `-fsanitize=address`-style options are now passed via `-C
link-args` through `RUSTFLAGS`. This obviates the need for the shell
script.
* The `-C default-linker-libraries`, disabling `-nodefaultlibs`, is
passed through `RUSTFLAGS`, which is necessary to ensure that
`-fsanitize=address` links correctly.
* The `-C linker` option is passed to ensure we're using the same C
compiler as normal C code, although it has a bit of hackery to only
get the `gcc` out of `gcc -std=c99`
