Implement dynamic loading of GnuTLS on Windows.
* lisp/term/w32-win.el (dynamic-library-alist): Add `gnutls'.
* nt/INSTALL: Clarify GnuTLS support.
* src/callproc.c, src/emacs.c: Include lisp.h before src/w32.h, not after.
* src/gnutls.c (Qgnutls_dll): Define.
(DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
(gnutls_*): Declare function pointers.
(init_gnutls_functions): New function to initialize function pointers.
(emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
(emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
(emacs_gnutls_write, emacs_gnutls_read)
(emacs_gnutls_handle_error, Fgnutls_error_fatalp)
(Fgnutls_available_p): New function.
(Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
(syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
(syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
* src/gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
(emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
Declare.
* src/w32.c (QCloaded_from, Vlibrary_cache): Define.
(w32_delayed_load): Move from image.c. When loading a library, record
its filename in the :loaded-from property of the library id.
(globals_of_w32) <QCloaded_from, Vlibrary_cache>:
Initialize and staticpro them.
(emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
* src/image.c: Include w32.h.
(Vimage_type_cache): Delete.
(syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
(CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
(w32_delayed_load): Move to w32.c.
* src/process.c: Include lisp.h before src/w32.h, not after.
(wait_reading_process_output): Call emacs_gnutls_record_check_pending
instead of gnutls_record_check_pending.
* src/w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
