Remove macro hacks for internal vs. external functions. Part 2 and last.

* src/visibility.h: Remove remaining define/undef hacks for symbol
visibility.  Add macros to detect the use of the public functions.
Change all affected functions by replacing them by the x-macros.
* src/g10lib.h: Add internal prototypes.
(xtrymalloc, xtrycalloc, xtrymalloc_secure, xtrycalloc_secure)
(xtryrealloc, xtrystrdup, xmalloc, xcalloc, xmalloc_secure)
(xcalloc_secure, xrealloc, xstrdup, xfree): New macros.

--

The use of xmalloc/xtrymalloc/xfree is a more common pattern than the
gcry_free etc. functions.  Those functions behave like those defined
by C and thus for better readability we  use these macros and not
the underscore prefixed functions.
