Update verilog-mode.el from master.

Update verilog-mode.el from master.

* progmodes/verilog-mode.el (verilog-pretty-expr): Rework
verilog-pretty-expr to handle new assignment operators in system
verilog, such as += *= and the like.
(verilog-assignment-operator-re): Regular expression to find the
assigment operator in a verilog assignment.
(verilog-assignment-operation-re): Regular expression to find an
assignment statement for pretty-expr.
(verilog-in-attribute-p): Query returns true if point is in an
attribute context; used to skip these for expression line up from
pretty-expr.
(verilog-in-parameter-p): Query returns true if point is in an
parameter definition context; used to skip these for expression
line up from pretty-expr.
(verilog-in-parenthesis-p): Query returns true if point is in a
parenthetical expression, specifically ( ) but not [ ] or { };
used by pretty-expr.
(verilog-just-one-space): If there is no space, don't add one.
(verilog-get-lineup-indent-2): Specifically skip just attribute
contexts for expression lineup, rather than skipping all
parenthetical expressions.
(verilog-calculate-indent): Fix comment, and fix indent.
(verilog-do-indent): Indent declarations in lists (suggested by
Joachim Lechner).
(verilog-mode-abbrev-table): Populate abbrev mode with the various
skeleton items.
(verilog-sk-ovm-class): Add skeleton for OVM classes (reported
by Alain Mellan).

`verilog-auto-star-save' off.  Reported by Dan Dever.
(verilog-auto-reset, verilog-read-always-signals)
(verilog-auto-reset-blocking-in-non): Fix AUTORESET including
temporary signals in reset list if
verilog-auto-reset-blocking-in-non is nil, and match assignment
style to each signal's assignment type, bug381.  Reported by
Thomas Esposito.
(verilog-sk-uvm-class, verilog-uvm-begin-re, verilog-uvm-end-re)
(verilog-uvm-statement-re): Support UVM indentation and

non-numeric vector width.  Reported by Alex Reed.

detecting signals with parameter widths. Reported by Alex Reed.

whitespace in auto expansion, bug371.  Reported by Brad Dobbie.

Fix verilog-scan-cache corruption when running user AUTO expansion
hooks that call indentation routines.

identifiers.

automatics, as long as they start with AUTO.
(verilog-batch-diff-auto, verilog-diff-auto)
(verilog-diff-function): Add `verilog-diff-auto' and bind to
"C-c?"  to report differences in AUTO expansion, ignoring spaces.

(verilog-in-paren-quick, verilog-re-search-backward-quick)
(verilog-re-search-forward-quick, verilog-syntax-ppss): Fix
calling `syntax-ppss' when inside auto expansions as the ppss hook
is disabled and its cache will get corrupt, causing AUTOS not to
expand.  Instead use only -quick functions.

`default_nettype none.  Reported by Julian Gorfajn.
