Inhibit buffer hooks in temporary buffers
Give get-buffer-create an optional argument to inhibit buffer hooks in internal or temporary buffers for efficiency (bug#34765). * etc/NEWS: Announce new parameter of get-buffer-create and generate-new-buffer, and that with-temp-buffer and with-temp-file now inhibit buffer hooks. * doc/lispref/buffers.texi (Buffer Names): Fix typo. (Creating Buffers): Document new parameter of get-buffer-create and generate-new-buffer. (Buffer List, Killing Buffers): Document when buffer hooks are inhibited. (Current Buffer): * doc/lispref/files.texi (Writing to Files): Document that with-temp-buffer and with-temp-file inhibit buffer hooks. * doc/lispref/internals.texi (Buffer Internals): Document inhibit_buffer_hooks flag. Remove stale comment. * doc/misc/gnus-faq.texi (FAQ 5-8): * lisp/simple.el (shell-command-on-region): Fix indentation. * lisp/files.el (kill-buffer-hook): Document when hook is inhibited.

(with-temp-file, with-temp-buffer, with-output-to-string): * lisp/json.el (json-encode-string): Inhibit buffer hooks in buffer used. * src/buffer.c (run_buffer_list_update_hook): New helper function. (Fget_buffer_create): Use it. Add optional argument to set inhibit_buffer_hooks flag instead of comparing the buffer name to Vcode_conversion_workbuf_name. All callers changed. (Fmake_indirect_buffer, Frename_buffer, Fbury_buffer_internal) (record_buffer): Use run_buffer_list_update_hook. (Fkill_buffer): Document when buffer hooks are inhibited. Use run_buffer_list_update_hook. (init_buffer_once): Inhibit buffer hooks in Vprin1_to_string_buffer. (Vkill_buffer_query_functions, Vbuffer_list_update_hook): Document when hooks are inhibited. * src/buffer.h (struct buffer): Update inhibit_buffer_hooks commentary. * src/coding.h (Vcode_conversion_workbuf_name): * src/coding.c (Vcode_conversion_workbuf_name): Make static again since it is no longer needed in src/buffer.c.

Mention window-selection-change-functions alongside buffer-list-update-hook. * test/src/buffer-tests.el: Fix requires. (buffer-tests-inhibit-buffer-hooks): New test.
