This fixes https://puszcza.gnu.org.ua/bugs/index.php?502.
* src/findkey.c (gdbm_bucket_element_valid_p): Verify also if the
key/data pair ends at a valid file offset.
(_gdbm_read_entry): Set up the cache data only on success.
* src/gdbmdefs.h (gdbm_bucket_element_valid_p): Remove declaration.
(gdbm_file_info): New member 'file_size' keeps the recently retrieved
value of the file size. It is invalidated wherever data is written to
the database.
* src/fullio.c (_gdbm_full_write,_gdbm_file_extend): Invalidate
dbf->file_size.
* src/gdbmopen.c (gdbm_fd_open): Initialize file_size to -1.
(_gdbm_file_size): New function.
* src/mmap.c (_gdbm_file_size): Remove.
* src/proto.h (_gdbm_file_size): New proto.

* src/mmap.c (_gdbm_file_extend): Move to ...
* src/fullio.c: ... here
* src/proto.h (_gdbm_file_extend): New proto.
* src/gdbmopen.c (gdbm_fd_open): Make sure the file size equals
header->next_block.
* src/gdbmsetopt.c [!HAVE_MMAP]: Don't disable GDBM_GETFLAGS.
* src/update.c (_gdbm_end_update): Make sure disk file ends on
header->next_block.

* src/bucket.c (_gdbm_get_bucket): Improve validation.
* src/fullio.c (_gdbm_full_read,_gdbm_full_write): Don't overwrite
an already set error.
* src/gdbm.h.in (GDBM_WRONG_OFF_T): Merge with GDBM_BAD_FILE_OFFSET.
(GDBM_BAD_HEADER): New error code.
* src/gdbmdump.c (_gdbm_dump_ascii): Check for database error code.
* src/gdbmerrno.c (gdbm_errlist): Add GDBM_BAD_HEADER
* src/gdbmopen.c (validate_header: Imporve logic.
(_gdbm_init_cache): Initialize bucket_cache
* src/gdbmseq.c (gdbm_firstkey): Check return value
from _gdbm_get_bucket.
* src/mmap.c (_gdbm_mapped_remap): Bail out if current position is bigger
than file size.

sure the error gets reported in debug output.
* src/fullio.c (_gdbm_full_read)
(_gdbm_full_write): Return -1 and set gdbm_errno
on error.
* src/bucket.c: Use GDBM_SET_ERRNO(2?) or
GDBM_DEBUG where necessary.
