This is a modified set of function as used by gpg for ages. These are
quite useful functions and will be needed internally for some other
planned features.  The idea is to make their counterparts in gnupg
wrapper around those new functions.

After we have moved the secure memory stuff from Libgcrypt to here we
can also implement a GPGRT_STRLICT_SECMEM flag to allow allocating
strings here ion secure memory.  For now we only have the WIPE flag
which wipes the memory on free.
