This is basically a continuation of the work from #1002 but her for the
camlibs directory. The purpose was to replace spaces as a means for
indentation with tab characters.
Note: there are some files which are still offending the general
rule but are (mostly) consistent within themselves. I let them be for
the moment. Fixing them would basically replace the whole file.
Also: there are still a ton of whitespace related inconsistencies like
"x=10" vs "x = 10" or "func(10)" vs "func (10)".
This is a whitespace only change (if you include newlines as whitespace).
This replaces the verbose and error prone pattern of calling
str = malloc(strlen("some value is 12345678"));
sprintf(str, "some value is %d", val)
with
str = aprintf(some value is %d", val);
This is similar to the GNU function asprintf() but returns the pointer
instead of assigning it to the first parameter. It uses the existing
gpi_vsnprintf(fmt, va_list) function.
* remove trailing whitespace in *.c/*.h files
This is now 'enforced' via .editoconfig. Do it here once to prevent random
ws changes during editing.
* Cleanup intra-line whitespace in large submenu tables in config.c
Consistently use spaces to layout columns, to make it independent of tab
size.
