Closing these file descriptors can hide sanitiser logs.
Instead, flush the logs before tor exits, using fsync().
Some Windows environments don't have fsync(), so we check
for it at compile time.
Fixes bug 33087; bugfix on 0.4.1.6.
"ours" merge, because simiar BridgeDistribution fixes have already
been merged to maint-0.4.3. (See 32753.)
The stem changes in 33075 have already been merged to maint-0.4.3,
so this "ours" merge does not affect them.
This patch ensures that we always lowercase the BridgeDistribution from
torrc in descriptors before submitting it.

Between 042 and 043, the dirauth options were modularized so this merge commit
address this by moving the AuthDirRejectUncompressedRequests to the module
along with a series of accessors.

Authorities were never sending back 503 error code because by design they
should be able to always answer directory requests regardless of bandwidth
capacity.
However, that recently backfired because of a large number of requests from
unknown source using the DirPort that are _not_ getting their 503 code which
overloaded the DirPort leading to the authority to be unable to answer to its
fellow authorities.
This is not a complete solution to the problem but it will help ease off the
load on the authority side by sending back 503 codes *unless* the connection
is from a known relay or an authority.

This controls the previous feature added that makes dirauth send back a 503
error code on non relay connections if under bandwidth pressure.

The configured, within the torrc or hardcoded, directory authorities addresses
are now added to the nodelist address set.

We separate v4 and v6 because we often use an IPv4 address represented with
a uint32_t instead of a tor_addr_t.
This will be used to also add the trusted directory addresses taken from the
configuration.
The trusted directories from the consensus are already added to the address
set from their descriptor.

That function is only used to test the global bucket write limit for a
directory connection.
It should _not_ be used for anything else since that function looks to see if
we are a directory authority.
Rename it to something more meaningful. No change in behavior at this commit,
only renaming.
