Description:- There is a possibility of negative array index
write associated with the function "terminal_writec()". This
is due to the assumption that there is a possibility of
getting -1 return value from the function call
"ct_visual_char()".
Analysis:- The function "terminal_writec()" is called only
from "em_delete_or_list()" and "vi_list_or_eof()" and both
these functions deal with the "^D" (ctrl+D) signal. So the
"size_t len" and "Char c" passed to "ct_visual_char()" (when
called from "terminal_writec()") is always 8 (macro
VISUAL_WIDTH_MAX is passed whose value is 8) and 4 (ASCII
value for "^D"/"ctrl+D") respectively.
Since the value of "c" is 4, "ct_chr_class()" returns -1
(macro CHTYPE_ASCIICTL is associated with -1 value). And
since value of "len" is 8, "ct_visual_char()" will always
return 2 when it is called from "terminal_writec()".
So there is no possible case so that we encounter a negative
array index write in "terminal_writec()". But since there is
a rare posibility of using "terminal_writec()" in future
enhancements, it is good handle the error case as well.
Fix:- A condition is added in "terminal_writec()" to check
whether "ct_visual_char()" is returning -1 or not. If the
return value is -1, then value 0 is returned to its calling
function "em_delete_or_list()" or "vi_list_or_eof()", which
in turn will return CC_ERROR.
NOTE:- No testcase is added since currently there is no
possible scenario to encounter this error case.
Fixed failing tests in sys_vars as we have now stricter checking of setting of variables.

I manually checked that all the conflicting InnoDB changes are in 5.5 already.
Two things I am not sure about - I commented them with XXX in this patch.
I will further check with the authors of the changesets whether these things
should be present or not.

BREAKS SOURCE RELEASE BUILD
Some of the required files were not getting copied while
performing 'make dist' and hence the build failed for
the created distribution source.
Added the missing files to Makefile.am.

WITH LIBEDIT
Libedit won't build on platforms that do not provide
"sys/cdefs.h".
Removed the inclusion of cdefs.h from all files
other that sys.h, which includes this file only
when the header is found while configuring.

.editrc on linux.
MySQL client when build with libedit support ignores
.editrc at startup.
The reason for this regression was the incluison of a
safety check, issetugid(), which is not available on
some linux platforms.
Fixed by adding an equivalent check for platforms which
have get[e][u|g]id() set of functions.
