tar: don't export names that aren't used elsewhere

* src/common.h (file_dumpable_p, gid_to_chars, major_to_chars):
(minor_to_chars, mode_to_chars, uid_to_chars, uintmax_to_chars):
(string_to_chars, dumpdir_creat0, dumpdir_create, dumpdir_free):
(dumpdir_locate, dumpdir_next, dumpdir_first, gid_from_header):
(major_from_header, minor_from_header, mode_from_header):
(time_from_header, uid_from_header, quote_copy_string, request_stdin):
(xheader_init, transform_header_name):
Remove declarations; these are no longer exported from their modules.
(GID_TO_CHARS, MAJOR_TO_CHARS, MINOR_TO_CHARS, MODE_TO_CHARS):
(UID_TO_CHARS, UINTMAX_TO_CHARS, UNAME_TO_CHARS, GNAME_TO_CHARS):
Move to src/create.c, since no other module uses these.
(GID_FROM_HEADER, MAJOR_FROM_HEADER, MINOR_FROM_HEADER):
(MODE_FROM_HEADER, TIME_FROM_HEADER, UID_FROM_HEADER):
Move to src/extract.c, since no other module uses these.
(dumpdir_t, dumpdir_iter_t): Remove; no longer used.
* src/create.c (gid_to_chars, major_to_chars, minor_to_chars):
(mode_to_chars, uid_to_chars, uintmax_to_chars, string_to_chars):
(file_dumpable_p): Now static.
* src/incremen.c (dumpdir_create0, dumpdir_create, dumpdir_free):
(dumpdir_locate, dumpdir_next, dumpdir_first): Now static.
(scan_directory, write_directory_file_entry):
Use struct dumpdir_iter * rather than dumpdir_iter_t.
* src/list.c (gid_from_header, major_from_header, minor_from_header):
(mode_from_header, time_from_header, uid_from_header):
(transform_member_name): Now static.
* src/misc.c (quote_copy_string): #if 0 out, as it's not used
anywhere.
* src/system.c (wait_for_grandchild): Now static.
* src/tar.c (request_stdin): Now static.
* src/xheader.c (xheader_init): Now static.
