  Hi,

This series collects a set of minor improvements, refactorings, and
general knick-knacks from my work queue.

The primary goal of this series is to prepare the codebase for upcoming
SFrame V3 support. It includes some code hygiene, such as cleaning
up abstractions between BFD/GAS and libsframe, implementing
internal-only FDE representations, and introducing SFRAME_V2_* macros to
clarify versioning.

Additionally, this series includes a few specific fixes regarding RA
tracking (including a revert) and corresponding testsuite updates.

No regressions seen on x86_64-linux, aarch64-linux, s390x-linux and few
other tested targets.

Thanks,

Indu Bhagat (13):
