[PATCH v3 0/3] malloc: Enable profiling dlmalloc with valgrind

[Sean Anderson]

This series adds support for running valgrind against U-Boot's internal
malloc. This allows for much more useful reports to be generated.

Some example output of valgrind run against u-boot/master with this branch
applied may be found at [1]. Note that valgrind gives up around acpi. This
feature still needs a lot of work on suppressions/hints to filter out the noise
properly.

Changes in v3:
- Fix some warnings by converting some macros to use
  VALGRIND_DO_CLIENT_REQUEST_STMT
- Fix an additional rEALLOc branch missing VALGRIND_RESIZEINPLACE_BLOCK

Changes in v2:
- Fix one branch of rEALLOc missing a VALGRIND_*_BLOCK call
- Add some additional suppressions for cALLOc and rEALLOc
- Simplify calloc clearing logic
- Drop incorrect sbrk patch
