8d23cb0373 Extended functionality of the trap builtin, which now closely follows 
POSIX recommendations.

	- trap now accepts signal names and signal numbers
	  e.g. INT, SIGINT, 2
	- added option -l that outputs a list of valid signals
	- added signal EXIT to list of valid signals
	- a `-' in the action part will reset specified signal to their
	  default behaviour
	- changed standard output format to make it suitable as an input
	  to another shell that achieves the same trapping results

84d782a52f __CONCAT does token pasting, not string concatnation. if something like: 
__CONCAT("PATH=",_PATH_STDPATH);
actually works to concantate strings, it's because the preprocessor expands
it into "PATH=""whatever _PATH_STDPATH is" as separate strings, and then
ANSI string concatenation is performed on that.  It's more straightforward
to just use ANSI string concatenation directly, and newer GCCs complain
(rightly) about mis-use of token pasting.

8e2797bc1e PR/11283: Hubert Feyrer: random memory corruption executing commands: 
Fix from FreeBSD:

    growstackblock() sometimes relocates a stack_block considered empty
    without properly relocating stack marks referencing that block.
    The first call to popstackmark() with the unrelocated stack mark
    as argument then causes sh to abort.

    Relocating the relevant stack marks seems to solve this problem.

    The patch changes the semantics of popstackmark() somewhat.  It can
    only be called once after a call to setstackmark(), thus cmdloop() in
    main.c needs an extra call to setstackmark().

362c3e31c9 The builtin . (dot) command no longer sees the current working directory 
even if the specified file is not in the PATH.
This change enforces security and makes it conform to POSIX.

Closes PR #6794.
I thought Christos committed this but not appeared yet. :)

The setstackmark()/popstackmark() pair in dotcmd(), used for freeing
stack storage possibly allocated by find_dot_file(), is redundant for now
since dotcmd() is surrounded by another pair in evalcommand().
This redundancy, however, may help future modifications
(suggested by Christos).

e1849b79b1 PR/6213: Urban Boquist: /bin/sh does not handle a trapped signal correctly 
The problem was that system calls got restarted after a signal,
	 instead of returning EINTR. Thus the read builtin, had no way to
	 know that a signal occured that could change the course of execution.
	 Since the code has sprinkled checks for EINTR all over the place,
	 it is supposed to work properly with non restartable syscalls.
	 The fix is to use siginterrupt(signo, 1), before setting a signal
	 handler, to make sure that system calls don't get restarted.

sleep
    cmd='set `type "sleep"`; eval echo \$$#'
    which=`eval $cmd`
    echo $which

because the region did not get recorded at all, and it was interpreted as
a single word. I modified the code to keep track when the result of a
backquote expansion has been recorded to avoid recording it twice. I still
feel that this is not the right fix... More to come.

5accccd051 Fix problem introduced in yesterday's commit that broke both signed and 
unsigned character machines. So that people don't have to reverse engineer
this again:
	mksyntax detects if characters are signed or not and builts a syntax
	table that has a base of 129 for signed characters or 1 for unsigned
	characters. This is so the largest negative signed char [-128] + the
	base == 1. 0 is special and means end of file in both cases. PEOF
	is -1 for the unsigned character case and -129 for the signed
	character case, so that syntax[PEOF + base] == syntax[0] == CEOF
	So PEOF has to be -1, but it is explicitly compared with
	unsigned characters on machines where characters are unsigned.
	The quick fix is to define UPEOF the (unsigned char) version of PEOF
	and use that. A better fix is to always use unsigned characters
	when referencing symbol table entries, but that would require
	extensive changes to the shell. So to summarize

	syntax[0] == CEOF, base + PEOF == 0

		unsigned	signed
	base	1		129
	PEOF	-1		-129
