This patch ensures that we return TOR_COMPRESS_BUFFER_FULL in case we
have a input bytes left to process, but are out of output buffer or in
case we need to finish where the compression implementation might need
to write an epilogue.

The confparse field has type UINT, which corresponds to an int
type. We had uint32_t.
This shouldn't cause trouble in practice, since int happens to
4-bytes wide on every platform where an authority is running. It's
still wrong, though.
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.
New approach, suggested by Taylor: During testing builds, we
initialize a union member of an appropriate pointer type with the
address of the member field we're trying to test, so we can make
sure that the compiler doesn't warn.
My earlier approach invoked undefined behavior.
Also demote a log message that can occur under natural causes
(if the circuit subsystem is missing descriptors/consensus etc.).
The HS subsystem will naturally retry to connect to intro points,
so no need to make that log user-facing.
So we can track them more easily in the logs and match any open/close/free
with those identifiers.

This removes the "nickname" of the cannibalized circuit last hop as it is
useless. It now logs the n_circ_id and global identifier so we can match it
with other logging statement.

Prior to the log statement, the circuit n_circ_id value is zeroed so keep a
copy so we can log it at the end.
