Sergey Poznyakoff ae23a57d70 Improve option sanity checking ...

Any two conflicting options are reported only if they both occur in
the command line.  Otherwise, options defined in the command line
silently override those set in the TAR_OPTIONS environment variable.

* src/common.h (option_source): New enum.
(option_locus): New struct.
* src/names.c (name_elt): New member: line.
(name_add_file): Initialize line.
(read_name_from_file): Keep track of input line number for diagnostic
purposes.
(handle_option): Take a pointer to struct name_elt as 2nd parameter;
pass locus info to more_options().
* src/tar.c (tar_args): New member: loc.
(option_class): New enum.
(optloc_save,optloc_lookup)
(option_set_in_cl,optloc_eq): New functions.
(set_use_compress_program_option): Take into account option location.
(set_old_files_option): New function.
(parse_opt): Keep track of option locations.
(more_options): Improve error reporting.
(parse_default_options): New function.
(decode_options): Parse TAR_OPTION and command line separately.
Options from the latter silently override those from the former.

* lib/prepargs.c: Remove.
* lib/prepargs.h: Remove.
* lib/Makefile.am: Update.
