* 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.

* src/visibility.h: Remove almost all define/undef hacks for symbol
visibility. Add macros to detect the use of the public functions.
Change all affected functions by prefixing them explicitly with an
underscore and change all internal callers to call the underscore
prefixed versions. Provide convenience macros from sexp and mpi
functions.
* src/visibility.c: Change all functions to use only gpg_err_code_t
and translate to gpg_error_t only in visibility.c.
--
The use of the macro magic made if hard to follow the function calls
in the source. It was not easy to see if an internal or external
function (as defined by visibility.c) was called. The change is quite
large but hopefully makes Libgcrypt easier to maintain. Some
function have not yet been fixed; this will be done soon.
Because Libgcrypt does no make use of any other libgpg-error using
libraries it is useless to always translate between gpg_error_t and
gpg_err_code_t (i.e with and w/o error source identifier). This
translation has no mostly be moved to the function wrappers in
visibility.c. An additional advantage of using gpg_err_code_t is that
comparison can be done without using gpg_err_code().
I am sorry for that large patch, but a series of patches would
actually be more work to audit.

While checking the new code I figured that the auto-computation of Q
must have led to a segv. It seems we had no test case for that.

--
gcry_mpi_ec_p_new() was a specialized version of the more general new
gcry_mpi_ec_new(). It was added to master only a few days ago, thus
there should be no problem to remove it. A replacement can easily be
written (cf. t-mpi-point.c).
Note that gcry_mpi_ec_set_mpi and gcry_mpi_ec_set_point have not yet
been tested.

--
This part finishes the basic API to do EC math. It provides a wrapper
around all internal functions. tests/t-mpi-point.c may be useful as
sample code. Eventually we will add function to retrieve curve
parameters etc.
