d3c5202f50 Allow strings to span multiple lines - newlines and any leading
whitespace are removed, as well as any following comments that couldn't
be part of a format. This allows long formats or other strings to be
annotated and indented.

b3782d2dc8 Instead of using a custom parse function to process {}, treat it as a
set of statements and parse with yacc, then convert back to a string as
the last step. This means the rules are consistent inside and outside
{}, %if and friends work at the right time, and the final result isn't
littered with unnecessary newlines.

6f03e49e68 Use the internal representation for UTF-8 keys instead of wchar_t and
drop some code only needed for that.

34804f2709 When parsing strings, put all commands in one group even if there are
newlines. This means that for example bind q { a \n b } and bind q "a ;
b" are the same. Also log commands in different groups separated by ;;
rather than ; (a command list like this should never be user visible).

cc8b41f294 Add a way to mark environment variables as "hidden" so they can be used
by tmux but are not passed into the environment of new panes.

e388702260 Ignore empty commands rather than adding them to the command list rather
than trying to skip them later, fixes problem reported by M Kelly.

f4c7141f5d Do not lazily use BUFSIZ for "I don't care what size" when building
strings because it is only guaranteed to be 256 bytes and even the
default 1024 is not always enough. Reported by Gregory Pakosz.

45203582ff A couple of minor parser changes around conditions: 1) only treat #{
specially after a condition, otherwise as a comment (which is more as
most people expect) 2) allow formats to be quoted after a condition.

900238a306 yacc(1) copies its union so it is not a good place to store
TAILQ_HEADs. Allocate them instead. Found from a problem reported by

c17edd594e The line number needs to be updated only after the \n is processed by
the parser, so store a flag and update it next time around. Also each
new line needs its own shared data.

6b332127ca Add an additional {} syntax for defining strings in the configuration
file, making it much tidier to define commands that contain other tmux
or shell commands (like if-shell). Also tweak bind-key to expect a
string if it is only given one argument, so {} can be used with it as
well. From Avi Halachmi.

6dee409981 Some other platforms doesn't support fmemopen(3) (not unexpectedly), so
don't use it - since we only use getc/ungetc on the file anyway it is
easy not to.

27bfb56ad5 Break the argument escaping code into a separate function and use it to
escape key bindings in list-keys. Also escape ~ and ; and $ properly.

723010ba72 Replace the split parser code (cfg.c and cmd-string.c) with a single
parser using yacc(1). This is a major change but is clearer and simpler
and allows some edge cases to be made more consistent, as well as
tidying up how aliases are handled. It will also allow some further
improvements later.

Entirely the same parser is now used for parsing the configuration file
and for string commands. This means that constructs previously only
available in .tmux.conf, such as %if, can now be used in string commands
(for example, those given to if-shell - not commands invoked from the
shell, they are still parsed by the shell itself).

The only syntax change I am aware of is that #{} outside quotes or a
comment is now considered a format and not a comment, so #{ is now a
syntax error (notably, if it is at the start of a line).

This also adds two new sections to the man page documenting the syntax
and outlining how parsing and command execution works.

Thanks to everyone who sent me test configs (they still all parse
without errors - but this doesn't mean they still work as intended!).

Thanks to Avi Halachmi for testing and man page improvements, also to
jmc@ for reviewing the man page changes.
