Subject: Rename VG_(malloc_usable_size) to VG_(cli_malloc_usable_size)
X-Git-Tag: svn/VALGRIND_3_11_0~1014
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4754dd70f26a52e719b2a2e384d1a7b329715fb7;p=thirdparty%2Fvalgrind.git

Rename VG_(malloc_usable_size) to VG_(cli_malloc_usable_size)
because it operates on the CLIENT arena. Given that VG_(malloc)
operates on the CORE arena, it was unexpected for VG_(mallos_usable_size)
to use a different arena.
Move function definition to the proper place (next to VG_(cli_malloc))
and fix call sites.
