9ad569c71d practracker: Add missing .may_include files
All of these files contain "*.h", except for:
* src/app/config/.may_include
* src/test/.may_include
which also contain "*.inc".

This change prevents includes of "*.c" files, and other
unusually named files.

11f283f561 config: Move server transport config into the relay module
This commit:
* creates feature/relay/transport_config.[ch],
* moves server transport config checks into them,
* exposes some code from src/app/config.c
  (we'll refactor it later in 29211), and
* adds thin wrappers to make the moved code compile.

No functional changes: the moved code is still enabled,
even if the relay module is disabled. (Some of the checks
are re-ordered, so the order of some warnings may change.)

389b37246e Remove overly strict assertions in transports.c.
This patch removes an overly strict tor_assert() and an ignorable BUG()
expression. Both of these would trigger if a PT was unable to configure
itself during startup. The easy way to trigger this is to configure an
obfs4 bridge where you make the obfs4 process try to bind on a port
number under 1024.

101bdeb02d doc: TCPProxy is not supported in TOR_PT_PROXY
Because we need to construct the URI using the TCPProxy configuration
but we don't have a standard URI scheme for haproxy yet, we decided to
not support TCPProxy in TOR_PT_PROXY now. There is no problem with
HTTPSProxy, Socks4Proxy, or Socks5Proxy because they all have standard
URI schemes.

16a0b7ed67 guard: Ignore marked for close circuit when changing state to open
When we consider all circuits in "waiting for guard" state to be promoted to
an "open" state, we were considering all circuits, even the one marked for
close.

This ultiamtely triggers a "circuit_has_opened()" called on the circuit that
is marked for close which then leads to possible undesirable behaviors within
a subsystem.

For instance, the HS subsystem would be unable to find the authentication key
of the introduction point circuit leading to a BUG() warning and a duplicate
mark for close on the circuit.

This commit also adds a unit test to make sure we never select marked for
close circuits when upgrading its guard state from waiting for guard to open.

Fixes #30871

8015979eeb num_bridges_usable(): only count configured bridges.
When this function was implemented, it counted all the entry guards
in the bridge set.  But this included previously configured bridges,
as well as currently configured ones!  Instead, only count the
_filtered_ bridges (ones that are configured and possibly reachable)
as maybe usable.

b98bcd789e Pathbias should continue to ignore previously ignored circs.
If circuit padding wants to keep a circuit open and pathbias used to ignore
it, pathbias should continue to ignore it.

This may catch other purpose-change related miscounts (such as timeout
measurement, cannibalization, onion service circuit transitions, and
vanguards).

aa360b255b Fix crash bug in PT subsystem.
This patch fixes a crash bug (assertion failure) in the PT subsystem
that could get triggered if the user cancels bootstrap via the UI in
TorBrowser. This would cause Tor to call `managed_proxy_destroy()` which
called `process_free()` after it had called `process_terminate()`. This
leads to a crash when the various process callbacks returns with data
after the `process_t` have been freed using `process_free()`.

We solve this issue by ensuring that everywhere we call
`process_terminate()` we make sure to detach the `managed_proxy_t` from
the `process_t` (by calling `process_set_data(process, NULL)`) and avoid
calling `process_free()` at all in the transports code. Instead we just
call `process_terminate()` and let the process exit callback in
`managed_proxy_exit_callback()` handle the `process_free()` call by
returning true to the process subsystem.
