Also rename ASSERT to VDO_ASSERT and ASSERT_LOG_ONLY to
VDO_ASSERT_LOG_ONLY.
But re-introduce ASSERT and ASSERT_LOG_ONLY as a placeholder
for the benefit of dm-vdo/indexer.

Otherwise, uds_ prefix is misleading (vdo_ is the new catch-all for
code that is used by vdo-only or _both_ vdo and the indexer code).

dm vdo: add memory allocation utilities2024-02-20T18:43:13+00:00Matthew Sakaimsakai@redhat.com2023-11-17T00:41:15+00:00urn:sha1:46766d4888ffdfd2bce91a6879bd6285a92a4881
This patch adds standardized allocation macros and memory tracking tools to
track and report any allocated memory that is not freed. This makes it
easier to ensure that the vdo target does not leak memory.
This patch also adds utilities for controlling whether certain threads are
allowed to allocate memory, since memory allocation during certain critical
code sections can cause the vdo target to deadlock.
