Add the profile library code to e2fsck

The profile library was originally written by Theodore Ts'o in 1995
for use in the MIT Kerberos v5 library.  It has been
modified/enhanced/bug-fixed over time by other members of the MIT
Kerberos team.  This version was originally taken from the Kerberos
v5 distribution, version 1.4.2, and radically simplified for use in
e2fsprogs.  (Support for locking for multi-threaded operations,
being able to modify and update the configuration file
programmatically, and Mac/Windows portability have been removed.
It has been folded into a single C source file to make it easier to
fold into an application program.)

+ * argv_parse.h --- header file for the argv parser.
+ *
+ * This file defines the interface for the functions argv_parse() and
+ * argv_free().
+ * 
+ ***********************************************************************
+ * int argv_parse(char *in_buf, int *ret_argc, char ***ret_argv)
+ *
+ * This function takes as its first argument a string which it will
+ * parse into an argv argument vector, with each white-space separated
+ * word placed into its own slot in the argv.  This function handles
+ * double quotes and backslashes so that the parsed words can contain
+ * special characters.   The count of the number words found in the
+ * parsed string, as well as the argument vector, are returned into
+ * ret_argc and ret_argv, respectively.
+ ***********************************************************************
+ * extern void argv_free(char **argv);
+ * 
+ * This function frees the argument vector created by argv_parse().
