relying on any other modules -- in m_libcbase. Also converted the 'size' parameters to functions like VG_(memcpy) and VG_(strncpy) from Int to SizeT, as they should be. Also removed VG_(atoll16) and VG_(toupper), which weren't being used. Also made VG_(atoll36) less flexible -- it now only does base-36 numbers instead of any base in the range 2..36, since base-36 is the only one we need. As part of that, I fixed a horrible bug in it which caused it to return incorrect answers for any number containing the digits 'A'..'I'! (Eg. for "A; it would return 17 instead of 10!) Had to disable the assertions in VG_(string_match), since this module can't see vg_assert, which wasn't ideal but also isn't a disaster. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3838
