(erc-dcc-get-file): Remove XEmacs compat code.

Fix erc-dcc server-close code and fix compilation warning

* lisp/erc/erc-dcc.el (erc-dcc-get-filter): We receive unibyte
data, so no need to convert to unibyte.
(erc-dcc-send-filter): Kill the process before killing the buffer
so that we're not queried about killing the process.

Make erc-dcc-server work again by making synchronous

* lisp/erc/erc-dcc.el (erc-dcc-server): :server and :nowait can't

Compilation fix for previous change

Compilation warning fix for disass.el

* lisp/emacs-lisp/disass.el (disassemble-1): Remove a
string-as-unibyte that probably doesn't do anything, because the
string in question should be unibyte anyway.  If the assert fails,
revert the patch.

CC Mode: replace an erroneous re-search-forward with search-forward

Fix text shaping of precomposed characters with HarfBuzz

* src/hbfont.c (hbfont_shape): Fix setting TO of lglyph for
the case when Lisp shape-gstring function performed some
compositions by itself.  This happens with hebrew.el.  See
https://lists.freedesktop.org/archives/harfbuzz/2019-June/007396.html
for the details of the problem this solves.

Move declaration of c-syntax-table-hwm to avoid compiler warnings.

the defsubst being in another file.

Revert previous ps-mode.el change

* lisp/progmodes/ps-mode.el (ps-mode-octal-region): Revert
previous change because the `string-make-unibyte' insertion was
the previous single change (in 2013) to this file, so it must have
some subtle meaning or other.

Add ps-mode-tests.el and remove a compilation warning

* lisp/progmodes/ps-mode.el (ps-mode-octal-region): Remove a
string-make-unibyte that apparently had no effect here.
* test/lisp/progmodes/ps-mode-tests.el: New file.

Suppress warnings in tildify.el

* lisp/textmodes/tildify.el (tildify--deprecated-ignore-evironments):
(tildify-tildify, tildify-mode): Suppress warnings about obsolete
internal function `tildify--pick-alist-entry'.  Apparently these
semi-deprecated functions rely on each other.

Revert "Compilation warning fix for byte-run.el"

* lisp/emacs-lisp/byte-run.el (macro-declaration-function):

Fix warning about obsolete func calling obsolete func in etags.el
