The `ResettableTimer` class' code did not account for the `function`
attribute to possibly call the timer, creating a deadlock because the
lock was already taken while calling the function. Move the function
call out of the lock.
Implement a downstream load/save handler in `revng.internal.api.Manager`
class which handles loading and saving files from a local directory to
a s3 server.
This commit fixes command line parsing of revng through the
REVNG_OPTIONS environment variable. Previously the env was prepended to
the actual command-line variables, now it's appended, allowing to
specify command line arguments that depend on `-load`s.
Package revng's python code in two wheels: `revng` and `revng_internal`.
The revng wheel contains the
`revng.{pipeline_description,model,tupletree}` modules, while the
`revng_internal` one everything under `revng.internal`.
