There are 3 types of extra payload:
- Directory index
- File block sizes
- Symlink target
This commit removes the type specific pointers and modifies the code
to use the payload area directly. To simplify the file block case and
mitigate alignment issues, the type of the extra field is changed to
sqfs_u32.
For symlink target, the extra field can simply be cast to a character
pointer (it had to be cast anyway for most uses). For block sizes,
probably the most common usecase, it can be used as is. For directory
indices, there is a helper function anyway.

If we don't store the padding location in the deduplication list,
the block deduplication might try to deduplicate across two files
with padding in between, which can't be done.

This is a fully automated search and replace, i.e. I ran this:
git grep -l uint8_t | xargs sed -i 's/uint8_t/sqfs_u8/g'
git grep -l uint16_t | xargs sed -i 's/uint16_t/sqfs_u16/g'
git grep -l uint32_t | xargs sed -i 's/uint32_t/sqfs_u32/g'
git grep -l uint64_t | xargs sed -i 's/uint64_t/sqfs_u64/g'
git grep -l int8_t | xargs sed -i 's/int8_t/sqfs_s8/g'
git grep -l int16_t | xargs sed -i 's/int16_t/sqfs_s16/g'
git grep -l int32_t | xargs sed -i 's/int32_t/sqfs_s32/g'
git grep -l int64_t | xargs sed -i 's/int64_t/sqfs_s64/g'
and than added the appropriate definitions to sqfs/predef.h
The whole point being better compatibillity with platforms that may
not have an stdint.h with the propper definitions.
