/**
* _exp_line_parse -- Parse a line in an exports file into a structure
* that holds all the parts of the line. An exports
* structure has a dict of netgroups and a dict of hosts.
*
* An export line looks something like this /test @test(sec=sys,rw,anonuid=0)
* or /test @test(sec=sys,rw,anonuid=0) hostA(sec=sys,rw,anonuid=0), etc.
*
* We use regexes to parse the line into three separate pieces:
* 1) The directory (exports.h -- DIRECTORY_REGEX_PATTERN)
* 2) The netgroup if it exists (exports.h -- NETGROUP_REGEX_PATTERN)
* 3) The host if it exists (exports.h -- HOST_REGEX_PATTERN)
*
* In this case, the netgroup would be @test(sec=sys,rw,anonuid=0)
* and the host would be hostA(sec=sys,rw,anonuid=0).
*
* @line : The line to parse
* @dir : Double pointer to the struct we need to parse the line into.
* If the parsing failed, the struct will point to NULL,
* otherwise it will point to a valid memory region that is
* allocated by this function.
* @parse_full : This parameter tells us whether we should parse all the lines
* in the file, even if they are not present in gluster's config.
* The gluster config holds the volumes that it exports so
* if parse_full is set to FALSE then we will ensure that
* the export file structure holds only those volumes
* that gluster has exported. It is important to note that
* If gluster exports a volume named '/test', '/test' and all
* of its subdirectories that may be in the exports file
* are valid exports.
* @ms : The mount state that holds the list of volumes that gluster
* currently exports.
*
* @return : success: GF_EXP_PARSE_SUCCESS on success, -EINVAL on bad arguments,
* -ENOMEM on memory allocation errors,
* GF_EXP_PARSE_LINE_IGNORING if we ignored the line,
* GF_EXP_PARSE_ITEM_FAILURE if there was error parsing
* failure: NULL
*
* The caller is responsible for freeing memory allocated by this function
* The caller should free this memory using the _exp_dir_deinit () function.
*
* Not for external use.
