Subject: include/context: Add module to keep track of build/test contexts
X-Git-Url: https://git.corax.cc/?a=commitdiff_plain;h=57ac132a39011cf8429695da4b8c91edc9944e83;p=foundry

include/context: Add module to keep track of build/test contexts

This commit adds the context module, which implements a set of functions
to track the state of a transaction across the buildsystem. This module
will be used to store the logs and artifacts associated with a context in
a central location, identified by the context identifier which is stored
in several of the IPC messages.
