Tests with the Debian image (which is generated with squashfs-tools,
so should be interpreted as ground truth) have showed that the count
is not stored off-by-one. The code was already doing the right thing,
but the documentation was wrong.

Combines all the type depenend attribute setting and inode 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.

This this commit, the code that is compiled and linked to produce
libsquashfs.so (and *only* libsquashfs.so) is released under the
terms and conditions of the GNU Lesser General Public license,
allowing 3rd party programs to dynamically link against it and still
being able to release their programs under a license of their choosing.
The libutil library is also relicensed, because it is statically linked
into libsquashfs.so. This does not affect the command line programs that
remain under the GPLv3.
At the current time, the two libraries do not contain any 3rd party
contributions and thus do not require anybodys consent other than mine
to change the licensing terms (unlike e.g. libfstree.a).
The libfstree.a and libsqfshelper.a utility libraries will also remain
under the GPLv3 license.
Going forward, some parts of libsqfshelper.a will be moved to
libsquashfs.so. The parts absorbed by libsquashfs.so will then also have
their licensing conditions changed *at that time*.
For the public headers, this commit adds the full boiler-plate comment
about the license, for the source files and internal headers, only the
SPDX identifier is changed.

The dir.h and inode.h headers contained meta data reader/writer
related functions. This commit moves them to the propper headers.

This in turn allows for removing most of the header inclusions
within the public headers.

Instead of including stddef/stdint/stdbool etc... all over the place,
move it to predef.h which is included from all other headers.

This commit adds a "predef.h" header to libsquashfs that exposes two
macros, SQFS_API and SQFS_INTERNAL that are used to explicilty set
the visibiliy of stuff that ends up in libsquashfs to default or
hidden.
For compatibillity with Windows which may at some point eventually be
considered, the SQFS_API define is set to dllexport IF the cpp symbol
SQFS_BUILDING_DLL is defined and set to import otherwise.

This commit adds a function to libsquashfs.so for writing generic inodes
to a meta writer and another function to libsqfshelper.a that turns a
tree node to an inode. That way, the tree serialization code can be
expressed in terms of those functions and a bulk of the independend code
can be moved over to libsquashfs.so

Move declarations for stuff that is defined in libsquashfs.so into the
public headers and declarations for stuff that isn't, out of there.
Also move the meta reader/writer helper functions to their respective
headers.
