This patch adds a deep-copy callback to sqfs_object_t and removes the
copying mechanism from sqfs_compressor_t. This is also interesting for
other types.

Make every dynamically allocated, opaque data structure inherit from
a common sqfs_object_t structure with common entry points (e.g. destroy).
This removes tons of public API functions and replaces them with a
simple sqfs_destroy instead. If semantics of the (until now implicit)
object system need to be extended, it can be much more conveniantely
done this way.

If the dir writer is used to create the directory table, it neccessarily
sees every single inode number and coresponding location for all inodes
that are referenced by the filesystem tree. This means it can easily
collect that information internally to create an export table later on.

Instead of using int or unsigned int for generic function flag
arguments, consistently use an unsigned, fixed size type.

This commit modifies the dir writer to store the directory index directly
in the payload area of the inode it creates. The size of the index in bytes
is stored in a seperate field. Storing the index is moved to the write
inode function.
The read inode function is in turn also modified to read the directory
index from disk and actually store it in the inode structure in memory
for later use.

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.
