adapt to ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}

Simplify CWARNFLAGS to use ${CC_WNO_ADDRESS_OF_PACKED_MEMBER}
which works for both clang and gcc, and remove compiler-specific
equivalents.

bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Initial commit of the fsck_udf(8) utility that checks and repairs UDF
filesystems on optical media as well as on disc images, harddisc partitions
and wedges.

New sentence, new line. Sort options.

remove an extra whitespace before else keyword.

Remove bogus assert() that checks if the size of the origional and the
reconstructed FIDs are the same after calling a function to see if it can be
made smaller. When there is accumulated slack in a sector this will be
reported but the assert would be triggered. While here also only copy the
reconstructed directory on an error.

If Volume Descriptor Sequence one reads in fine, we process it and free the
memory for the second Volume Descriptor Sequence. Fix the missing `else'
statement to prevent processing of the 2nd when it was freed. Fixes a
used-after-free case.

fix couple typos in comments.

branches: 1.14.2;
avoid double-free.

found by GCC 12.

Relax constraints on sequential media detection by checking for VAT format.
This allows fixing images of VAT formatted media too.

Fix endian bug in descriptor CRC length on updating a FE/EFE

Fix endian bug in allocation extents processing

Remove the error condition for these cases; the VAT LVExtension is
missing/corrupt but fsck_udf will reconstruct them anyway.

Prevent reading beyond the early_vat_location

Fix endian issues with fsck_udf/newfs_udf/makefs

Avoid assigned but unused compiler warnings when compiling with clang

fsck_udf(8): Nix trailing whitespace.

No functional change intended.

fsck_udf(8): Mark vat_length as ignored.

fsck_udf(8): Sprinkle __printflike and omit self-assignment.

Use PRI macros for uint64_t printf formats, %zu for size_t.

fsck_udf: match usage to man page; fix typos
