This patch adds some missing calls to set `reached_eof` of our handles
when various error conditions happens or when we close our handle (which
happens at `process_terminate()`.
See: https://bugs.torproject.org/28179
This patch adds some additional error checking after calls to
ReadFileEx() and WriteFileEx(). I have not managed to get this code to
reach the branch where `error_code` is NOT `ERROR_SUCCESS`, but MSDN
says one should check for this condition so we do so just to be safe.
See: https://bugs.torproject.org/28179
This patch makes us delay checking for whether we have an exit code
value (via GetExitCodeProcess()) until both stdout and stderr have been
closed by the operating system either by the process itself or by
process cleanup after termination.

This patch adds support for the new STATUS message that PT's can emit
from their standard out. The STATUS message uses the `config_line_t` K/V
format that was recently added in Tor.
See: https://bugs.torproject.org/28846
This patch changes the LOG pluggable transport message to use the recent
K/V parser that landed in Tor. This allows PT's to specify the log
severity level as well as the message. A mapping between the PT log
severity levels and Tor's log serverity level is provided.

Previously we had decoded the asn.1 to get a public key, and then
discarded the asn.1 so that we had to re-encode the key to store it
in the onion_pkey field of a microdesc_t or routerinfo_t.
Now we can just do a tor_memdup() instead, which should be loads
faster.
Previously, we would decode the PEM wrapper for keys twice: once in
get_next_token, and once later in PEM decode. Now we just do all of
the wrapper and base64 stuff in get_next_token, and store the
base64-decoded part in the token object for keys and non-keys alike.
This change should speed up parsing slightly by letting us skip a
bunch of stuff in crypto_pk_read_*from_string(), including the tag
detection parts of pem_decode(), and an extra key allocation and
deallocation pair.
Retaining the base64-decoded part in the token object will allow us
to speed up our microdesc parsing, since it is the asn1 portion that
we actually want to retain.
This patch makes sure that we terminate the event loop from the event
loop timer instead of directly in the process' exit handler. This allows
us to run the event loop an additional time to ensure that the SleepEx()
call on Windows is called and the data from stdout/stderr is delivered
to us.
Additionally we ensure that we don't try to read or write data from a
Unix process that have been terminated in the main loop, since its file
descriptors are closed at that time.

This patch changes the API of the Windows backend of the Process
subsystem to allow the dormant interface to disable the Process event
timer.

This patch changes our EVENT_TRANSPORT_LOG event to be EVENT_PT_LOG. The
new message includes the path to the PT executable instead of the
transport name, since one PT binary can include multiple transport they
sometimes might need to log messages that are not specific to a given
transport.
See: https://bugs.torproject.org/28179
This patch changes our process_t's exit_callback to return a boolean
value. If the returned value is true, the process subsystem will call
process_free() on the given process_t.
See: https://bugs.torproject.org/28179
This patch changes the slow process_t tests to use
run_main_loop_until_done() instead of do_main_loop() since
do_main_loop() initializes a lot of subsystem callbacks that we don't
need to run in our tests.
