Previously, 'quit' could cause remote endpoints to never get a
reply and thus sometimes hang. Ensure we always reply. Also,
give the application a chance to signal jsonrpc-error with the
served code=32000, meaning "no error".
* doc/lispref/text.texi (JSONRPC Overview): Rework section on
request dispatchers.
* lisp/jsonrpc.el (jsonrpc-connection-receive): Rework.
The info returned from `garbage-collect` is really handy to
track the evolution of the heap size, but sadly it's available only
at the cost of running a full GC, which has two big downsides:
it's slow, it affects what we're measuring, and it can't be used
in `post-gc-hook`.
So, this patch makes it available without running the GC.
* src/alloc.c (Fgarbage_collect_heapsize): New function, extracted from
`Fgarbage_collect`.
(Fgarbage_collect): Use it.
(syms_of_alloc): defsubr it.
* doc/lispref/internals.texi (Garbage Collection): Extract
documentation for it from that of `garbage-collect`.
* doc/lispref/internals.texi (Module Values, C Integer Types):
Mention that the example assumes Emacs was built with the
GMP library, not with mini-gmp. Mention stdckdint.h for
integer overflow checking, and mention Emacs integers
for values outside machine range.
Previously, if 'calc-string-maximum-character' wasn't a valid
character 'math-vector-is-string' would throw an error in the
comparison, leading to an incomplete display of the stack and a
cryptic error message. Instead, have 'math-vector-is-string'
return nil, which effectively disables the display of strings.
Refines feature introduced in bug#78528.
* doc/misc/calc.texi (Customizing Calc): Update description of
behavior for invalid 'calc-string-maximum-character'.

(XBM Images): Fix reference to incorrect number of properties.
(Multi-Frame Images, Other Image Types): Mention multi-frame WebP
support.

commit of 2019-05-17 "Clean up and simplify image-type setup". Fix
some commentary.
(image_pix_container_create_from_bitmap_data): Remove no longer used
frame parameter (bug#80191); this continues from commit of

A unique frame id is assigned to a new or cloned frame, and
reused on an undeleted frame.
The id facilitates unambiguous identification among frames that
share identical names or titles, deleted frames where a live
frame object no longer exists that we can resurrect by id, for
example via 'tab-bar-undo-close-tab'. It also aids debugging at
the C level using the frame struct member id.
Rewrite 'clone-frame' and 'undelete-frame' to not let bind
variables that 'make-frame' uses to avoid conflicts with nested
'make-frame' calls, for example via
'after-make-frame-functions'.

'frame--purify-parameters' to supply parameters explicitly.

performance issues.

clarity. Describe the `reusable-frames' behaviour first (as if it finds
a frame with a suitable tab then the `tab-name' entry is not used).
(display-buffer-in-new-tab): Use consistent wording.
* lisp/window.el (display-buffer--action-function-custom-type): Add the
display actions as customize choices for user options.

The direct cause of the problem in the bug report is that when
user runs treesit-font-lock-recompute-features to add the
emacs-devel feature in c-ts-mode's mode hook, the added query
for emacs-devel aren't compiled.
This change consists of two parts:
1. The immediate fix: validate and compile queries in
treesit-font-lock-recompute-features.
2. To make it more fool-proof, change treesit-font-lock-rules
back to compile the queries and make
treesit--compile-query-with-cache support compiled queries. This
way, as long as the query goes through treesit-font-lock-rules,
it'll be compiled eventually and not cause slow-down. I had to
add some c-level functions, but they're kind of overdue anyway,
so I don't have any problem adding them to the API.
* lisp/treesit.el (treesit--compile-query-with-cache): Support
compiled queries.
(treesit-font-lock-rules): Compile the queries (but not
eagerly).
(treesit-font-lock-recompute-features): Validate and compile
queries.
(treesit-major-mode-setup): Remove call to
treesit-validate-and-compile-font-lock-rules since it's now
called in treesit-font-lock-recompute-features.
* src/treesit.c (Ftreesit_query_eagerly_compiled_p):
(Ftreesit_query_source): New functions.
* doc/lispref/parsing.texi (Pattern Matching): Add manual
entries for the new functions.

* lisp/progmodes/project.el (project-files) <vc>: Look up the
value of 'project-vc-ignores' inside DIR rather than project root.
This allows this variable to be applied in external dirs as well.
(project-ignores) <vc>: Do likewise.
(project--value-in-dir): Ensure that DIR has a trailing slash.
The caller might pass the value without slash if produced
differently.
* test/lisp/progmodes/project-tests.el
(project-vc-ignores-in-external-directory): New test.
(project-vc-supports-files-in-subdirectory): Update the test,
considering the subtle change in behavior: the directory DIR
directly includes a .dir-locals.el which sets project-vc-ignores,
which wasn't previously applied because it wasn't set in the root.
