common/mischelp: use platform memory zeroing function for wipememory
* common/mischelp.h (wipememory): Replace macro with function
prototype.
(wipememory2): Remove.
* common/mischelp.c (wipememory): New.
* configure.ac (AC_CHECK_FUNCS): Check for 'explicit_bzero'.
--
In new wipememory function, memory is cleared through platform
provided secure memory zeroing function, SecureZeroMemory
or explicit_bzero.
If none of these is available, memset is called through
volatile function pointer to so that compiler won't optimize
away the call.
