Work around a bug in GnuTLS 3.7.11 and earlier: when built
statically, its mistakenly exports symbols hash_lookup and
hash_string, which collide with Emacs symbols of the same name,
preventing temacs from linking statically.  Problem reported by
Greg A. Woods (Bug#77476).

Because GnuTLS never uses hash_lookup or hash_string this issue
ordinarily doesn’t seem to prevent temacs from linking to GnuTLS
on GNU/Linux, as it’s linked dynamically and the dynamic linker
never needs to resolve references to either symbol.  However, I
suppose a clash or bug could occur even with dynamic linking if
Emacs later loads a module that uses either symbol.

Although GnuTLS should be fixed, Emacs should link statically to
current and older GnuTLS versions in the meantime, and it should
avoid potential problems with dynamic linking.  Renaming the two
clashing names is an easy way to do this.  For consistency with
the new name for hash_lookup, also rename hash_lookup_with_hash
and hash_lookup_get_hash.

* src/fns.c (hash_find_with_hash): Rename from hash_lookup_with_hash.
(hash_find): Rename from hash_lookup.
(hash_find_get_hash): Rename from hash_lookup_get_hash.
(hash_char_array): Rename from hash_string.
All uses changed.

* src/emacs-module.c (initialize_environment): Reorder assignments to
match declaration order in emacs-module.h.

This clarifies that the error isn't talking about an editing buffer.

* src/emacs-module.c (module_memory_buffer_too_small): Rename from
'module_buffer_too_small'.
(module_copy_string_contents, module_extract_big_integer): Adapt
callers.
(syms_of_module): Rename symbol 'buffer-too-small' to
'memory-buffer-too-small'.

The convention used by 'aref' and friends is that for
'args-out-of-range', the error data is a list (SEQ INDEX).  Use the same
convention for the vector-related module functions.

* src/emacs-module.c (check_vec_index): Use vector and index as error
data.

'args-out-of-range' means that some index argument isn't valid for a
given sequence/range, which isn't the case here.  Instead, define a new
error symbol to mean "user-supplied buffer is too small."  Since we
never specified nor tested which error symbol was signalled in this
case, changing it shouldn't cause severe breakages.

* src/emacs-module.c (module_buffer_too_small): New helper function.
(module_copy_string_contents, module_extract_big_integer): Use it.
(syms_of_module): Define 'buffer-too-small' error symbol.

The previous approach would incorrectly invalidate the returned module
values if another non-local exit occurred while dealing with a non-local
exit.  See Bug#65796.  Instead, allocate the values from the usual
environment storage, and return statically-allocated objects if that
fails.

* src/emacs-module.c (struct emacs_env_private): Turn non-local exit
symbol and data into normal Lisp objects.
(initialize_environment): Initialize them.
(mark_module_environment): Prevent them from being garbage-collected.
(module_signal_or_throw, module_non_local_exit_signal_1)
(module_non_local_exit_throw_1): Adapt uses.
(value_to_lisp): No longer scan for them with module assertions enabled.
(module_out_of_memory_signal, module_out_of_memory_data): New
statically-allocated module values to return in case of allocation
failure.
(syms_of_module): Initialize them.
(module_non_local_exit_get): Allocate module values normally.  If that
fails, return statically-allocated values.
