Change #278829

tar: support --one-top-dir=/abs/olute
It appears that people were using the --one-top-dir=DIR option
with an absolute file name, even though this behavior was
undocumented and erratic and recent tar versions rejected it.
Document and implement behavior that I hope people expect.
* src/extract.c (MAKEDIR_FULL_ESCAPE): New constant.
(make_directories): Let full directory names escape if
MAKEDIR_FULL_ESCAPE is passed.
(create_dir): Let DIR escape if it is the one-top-level dir
or an ancestor.
* src/misc.c (fdbase_opendir): Replace old CHILD_OFLAGS arg with
two new args CHILD and OFLAG, so that the functionalities can be
distinguished.  All callers changed.
(fdbase_escape): New function.
(fdbase): Use it, for simplicity.
* tests/onetop06.at: New test file.
* tests/Makefile.am (TESTSUITE_AT): Add it.
* tests/testsuite.at: Include it.
