Rename libsqfshelper to libcommon

2019-10-07T11:54:24+00:00

That is IMO less confusing and express what it is (i.e. what it has become) more clearly, i.e. common code shared by the utilities. Signed-off-by: David Oberhollenzer

Rename "hihglevel.h" to the more appropriate "common.h"

2019-10-07T11:49:40+00:00

It only contains helpers for _common_ stuff for all the utilities. The actual high level stuff has been moved to libsquashfs a while ago. Signed-off-by: David Oberhollenzer

Improve ABI backward & forward compatibillity

2019-10-07T10:22:05+00:00

- Padd the compressor config union - 128 bytes aught to be enough for everyone, i.e. future compressors. - Insist that the padding space is initialized to 0. If a field gets added to an existing compressor, it can test for 0 as a sentinel value. - Add a size field to the hook structure, aka "the Microsoft way". - The explanation is in the comment. - Don't make the Microsoft mistake of checking for >=, insist on *exact* size match. Future users will need a fallback if their hooks are rejected. But at least they will be rejected instead of silently not being used. - Add an unsupported flag check to the dir tree reader. - Add a basic abi unit test that, for now, checks the size of the compressor config struct fields.
