b0b8f7c30c Add support for Android's logging subsystem.
This patch adds support for Android's logging subsystem in Tor. When
debugging Android applications it is useful to be able to collect
information about the application running on the platform via the
various system services that is available on the platform.

This patch allows you to add "Log notice android" to your torrc and have
Tor send everything above and including the notice severity to Android's
ring buffer which can be inspected using the 'adb logcat' program.

See: https://bugs.torproject.org/24362

a9806af261 Create a CacheDirectory and KeyDirectory options.
They work the same as DataDirectory, but default slightly different.

Tor is not actually updated to use them yet.

c3c0a05f51 Add a new notion of "stamps" to be a fast 32-bit monotonic timestamp
The goal here is to replace our use of msec-based timestamps with
something less precise, but easier to calculate.  We're doing this
because calculating lots of msec-based timestamps requires lots of
64/32 division operations, which can be inefficient on 32-bit
platforms.

We make sure that these stamps can be calculated using only the
coarse monotonic timer and 32-bit bitwise operations.

192be00691 Make the DataDirectory option immutable.
By convention, the torrc options that the user sets are
unchangeable.  If we need to change them, we should be using a copy
that's stored in another field

To avoid trouble, I'm keeping DataDirectory as the name for the
field that the rest of Tor uses, and using DataDirectory_option for
the confparse-controlled field.

This commit also modernizes some older string handling code in the
DataDirectory normalization function.

ebab521525 Add new BridgeDistribution config option
Bridge relays can use it to add a "bridge-distribution-request" line
to their bridge descriptor, which tells BridgeDB how they'd like their
bridge address to be given out.

f1bf9bf819 Add __OwningControllerFD to allow controllers without controlports
This feature should help programs that want to launch and manage a
Tor process, as well as programs that want to launch and manage a
Tor instance in a separate thread.  Right now, they have to open a
controlport, and then connect to it, with attendant authentication
issues.  This feature allows them to just start with an
authenticated connection.

4d11a468b2 Correct two state-file variable types.
These should have been int, but we had listed them as unsigned.
That's an easy mistake to make, since "int" corresponds with either
INT or UINT in the configuration file.

This bug cannot have actually caused a problem in practice, since we
check those fields' values on load, and ensure that they are in
range 0..INT32_MAX.

5dea4b565f Add a BASE32_DIGEST_LEN define
Use this value instead of hardcoded values of 32 everywhere. This also
addresses the use of REND_DESC_ID_V2_LEN_BASE32 in
hs_lookup_last_hid_serv_request() for the HSDir encoded identity digest length
which is accurate but semantically wrong.

7cc9621d11 sched: Add Schedulers torrc option
This option is a list of possible scheduler type tor can use ordered by
priority. Its default value is "KIST,KISTLite,Vanilla" which means that KIST
will be used first and if unavailable will fallback to KISTLite and so on.

b2c56eacdd sched: Remove vanilla sched options that will be going away
- massive change to src/tgest/test_options.c since the sched options
  were added all over the place in it
- removing the sched options caused some tests to pass/fail in new ways
  so I assumed current behavior is correct and made them pass again
   - ex: "ConnLimit must be greater" lines
   - ex: "Authoritative directory servers must" line
- remove test_options_validate__scheduler in prep for new sched tests

93a8ed3b83 Make clients wait to refresh bridges when they have a recent descriptor
But when clients are just starting, make them try each bridge a few times
before giving up on it.

These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)

Fixes 23347, not in any released version of tor.

3124c921e7 Split the behavior of node_supports_ed25519_link_authentication().
Before, this function meant "can we connect to this node and
authenticate it using its ed25519 key?"  Now it can additionally
mean, "when somebody else connects to this node, do we expect that
they can authenticate using the node's ed25519 key"?

This change lets us future-proof our link authentication a bit.

Closes ticket 20895.  No backport needed, since ed25519 link
authentication support has not been in any LTS release yet, and
existing releases with it should be obsolete before any releases
without support for linkauth=3 are released.
