Add support for escaping special characters when doing filename completion.

For instance if the file name is "foo bar":
$ ls foo<TAB>
should get autocompleted to:
$ ls foo\ bar

Works for similar other characters too, which need escaping.

Also, add an accompanying test program to ensure the escaping is correct
in various scenarios (within quotes, without quotes, with other special characeters)

Thanks to Christos for reviews, help and feedback.

Start removing the WIDECHAR ifdefs; building without it has stopped working
anyway. (Ingo Schwarze)

Compile with WIDECHAR the same way the main Makefile does (Ingo Schwarze)

Userland now builds and uses terminfo instead of termcap.

OK: core@, jdc@

rename historyw -> history_w for consistency.
add wide tst code and make it the default.

Rename TEST/test.c to avoid problems when doing a cleandir on case-insensitive
file systems.
ok'ed christos.

Tokenization function enhancements:
* Make tok_init(), tok_end(), tok_reset(), tok_line() and tok_str()
publically available in <histedit.h>
* Documented the public functions in editline(3)
* Renamed tok_line() -> tok_str()
* Added new tok_line() which takes a "const LineInfo *" instead of
"const char *" (the former has "cursor" information), and optionally
return the argv index ("int *cursorc") and offset within that index
("int *cursorv"). This means that completion routines can use the
tokenization code to crack the line and easily find which word the
cursor is at. (mmm, context sensitive completion :)
* Fixed TEST/test.c when using "continuation" lines (unmatched quote
or \ at EOL), and added some more DEBUG messages including highlighting
where the cursor is (with a `_').

I got tired of typing a cc line.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Remove extraneous \n's in {err,warn}{,x}.

make sure this compiles cleanly and works.

- constify; passes all gcc and lint strict checks.
- add config.h [Jason Evans], to create a portable version of libedit that
can be easily compiled on other OS's.

More trailing white space.

Fix for api changes.

Initial revision

PR lib/54510: Fix file completion inside quotes which broke in rev 1.53

While there also fix handling character appending in the file completions when
inside quotes. For example when inside a quote, if the completion is a directory then
append a '/' but don't close the quote. On the other hand when inside a quote if the
completion is a file name and it is the only match then we can close the quote.

Perform quoting of filename completions when there are multiple matches as well

Quoting of special characters in filename completion was implemented for single match
case, this enables it for multiple matches as well. For example:

$ touch 'foo bar'
$ touch 'foo baz'
$ ls fo<TAB>
autocompletes to =>
$ ls foo\ ba
hitting <TAB> again shows:
foo bar foo baz

This required unescaping escape sequences generated during last completion
in order to find the word to complete.

While there, also update the test to include cases for multiple matches.

Handle filename autocompletion when the cursor is at a backslash or quote character

For example, handle following case:
$ touch 'foo bar'
$ ls foo\<TAB> --> $ ls foo\ bar

Also add test cases for this.

Add copyright and rcs header to the test program.
Also, remove a test case which was not supposed to be there.
(While that test case works with the changes I committed, testing that
test case with the test program is not possible in its current form. I'm
working on that.)
