8f89115efc dm vdo memory-alloc: rename vdo_do_allocation to __vdo_do_allocation
__vdo_do_allocation shouldn't be used outside of memory-alloc.h, so
add hidden prefix.

Also, tabify the vdo_allocate_extended macro.

46766d4888 dm vdo: add memory allocation utilities
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.
