faadbafba3 prop224: Add helper function to lookup HS objects
Add this helper function that can lookup and return all the needed object from
a circuit identifier. It is a pattern we do often so make it nicer and avoid
duplicating it everywhere.

d765cf30b5 prop224: Circuit has opened and ESTABLISH_INTRO cell
Add the entry point from the circuit subsystem of "circuit has opened" which
is for all type of hidden service circuits. For the introduction point, this
commit actually adds the support for handling those circuits when opened and
sending ESTABLISH_INTRO on a circuit.

Rendevzou point circuit aren't supported yet at this commit.

00a02a3a59 prop224: Service v3 descriptor creation and logic
This commit adds the functionality for a service to build its descriptor.
Also, a global call to build all descriptors for all services is added to the
service scheduled events.

0f104ddce5 prop224: Scheduled events for service
Add the main loop entry point to the HS service subsystem. It is run every
second and make sure that all services are in their quiescent state after that
which means valid descriptors, all needed circuits opened and latest
descriptors have been uploaded.

For now, only v2 is supported and placeholders for v3 actions for that main
loop callback.

key from a keypair (service) and from a public key (client). Those two

72832086e2 Use a single free-and-exit strategy in config_process_include.
This avoids a double-free when a pointer already freed with
tor_free(config_line) is freed again in the cleanup-and-exit code.

Fixes bug 23155.

649104fdb9 Remove a needless memwipe.
The interior of ctx here is already wiped by
crypto_digest_free(). This memwipe call only wiped the pointer
itself, which isn't sensitive.

89407bedf8 Tweak usage of get_current_working_dir() for tor_malloc() paranoia.
We assume that tor_free() is not required to be compatible with
the platform malloc(), so we need to use a strdup here.

bfe740f065 Refactor retrieving the current working directory
The GNU C Library (glibc) offers an function which allocates the
necessary memory automatically [0]. When it is available, we use that.

Otherwise we depend upon the `getcwd` function which requires a
preallocated buffer (and its size). This function was used incorrectly
by depending on the initial buffer size being big enough and otherwise
failing to return the current working directory. The proper way of
getting the current working directory requires a loop which doubles the
buffer size if `getcwd` requires it. This code was copied from [1] with
modifications to fit the context.

0265ced02b Remove usage of the PATH_MAX variable
GNU Hurd does not define the PATH_MAX variable. Using the variable on

3b646bf887 Fix ntohs() that should have been htons()
Fixes bug 23106; bugfix on 0.2.4.8-alpha.

Fortunately, we only support big-endian and little-endian platforms,
and on both of those, hton*() and ntoh*() behave the same.  And if
we did start to support middle endian systems (haha, no), most of
_those_ have hton*(x) == ntoh*(x) too.

5b03c7ba6d Fix check_expired_networkstatus_callback() if condition
The condition was always true meaning that we would reconsider updating our
directory information every 2 minutes.

If valid_until is 6am today, then now - 24h == 1pm yesterday which means that
"valid_until < (now - 24h)" is false. But at 6:01am tomorrow, "valid_until <
(now - 24h)" becomes true which is that point that we shouldn't trust the
consensus anymore.

Fixes #23091
