The GDB replay server sanity-checks that every packet it receives
matches what it expects from the serialized packet log. This mechanism
tripped for TestReproducerAttach.py on Linux, because one of the packets
(jModulesInfo) uses run-length encoding. The replay server was comparing
the expanded incoming packet with the unexpanded packet in the log. As a
result, it claimed to have received an unexpected packet, which caused
the test to fail.
This patch addresses that issue by expanding the run-length encoding
before comparing the packets.

This patch extends the reproducers to intercept calls to FindProcesses.
During capture it serializes the ProcessInstanceInfoList returned by the
API. During replay, it returns the serialized data instead of querying
the host.
The motivation for this patch is supporting the process attach workflow
during replay. Without this change it would incorrectly look for the
inferior on the host during replay and failing if no matching process
was found.
