Add argp implementation
Argp is an advanced support for parsing unix-style argument vectors. In addition to the common getopt interface, it provides automatic response to `--help' and `--version' options and use of custom parser in conjunction with argp native option parser, among others. Argp support is required by elfutils package and prelink. In uClibc argp functionalities has been moved from C library to libuargp.so Further the libc.so linker script contains an AS_NEEDED entry so that it doesn't need to link libuargp.so explicitely. Disable argp test if feature disabled.

+/* Argp example #3 -- a program with options and arguments using argp */
+
+/* This program uses the same features as example 2, and uses options and
+ arguments.
+
+ We now use the first four fields in ARGP, so here's a description of them:
+ OPTIONS -- A pointer to a vector of struct argp_option (see below)
+ PARSER -- A function to parse a single option, called by argp
+ ARGS_DOC -- A string describing how the non-option arguments should look
+ DOC -- A descriptive string about this program; if it contains a
+ vertical tab character (\v), the part after it will be
+ printed *following* the options
+
+ The function PARSER takes the following arguments:
+ KEY -- An integer specifying which option this is (taken
+ from the KEY field in each struct argp_option), or
+ a special key specifying something else; the only
+ special keys we use here are ARGP_KEY_ARG, meaning
+ a non-option argument, and ARGP_KEY_END, meaning
+ that all arguments have been parsed
+ ARG -- For an option KEY, the string value of its
+ argument, or NULL if it has none
+ STATE-- A pointer to a struct argp_state, containing
+ various useful information about the parsing state; used here
+ are the INPUT field, which reflects the INPUT argument to
+ argp_parse, and the ARG_NUM field, which is the number of the
+ current non-option argument being parsed
+ It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
+ given KEY wasn't recognized, or an errno value indicating some other
+ error.
+
+ Note that in this example, main uses a structure to communicate with the
+ parse_opt function, a pointer to which it passes in the INPUT argument to
+ argp_parse. Of course, it's also possible to use global variables
+ instead, but this is somewhat more flexible.
+
+ The OPTIONS field contains a pointer to a vector of struct argp_option's;
+ that structure has the following fields (if you assign your option
+ structures using array initialization like this example, unspecified
+ fields will be defaulted to 0, and need not be specified):
+ NAME -- The name of this option's long option (may be zero)
+ KEY -- The KEY to pass to the PARSER function when parsing this option,
+ *and* the name of this option's short option, if it is a
+ printable ascii character
+ ARG -- The name of this option's argument, if any
+ FLAGS -- Flags describing this option; some of them are:
+ OPTION_ARG_OPTIONAL -- The argument to this option is optional
+ OPTION_ALIAS -- This option is an alias for the
+ previous option
+ OPTION_HIDDEN -- Don't show this option in --help output
+ DOC -- A documentation string for this option, shown in --help output
+
+ An options vector should be terminated by an option with all fields zero. */
