- We can only pack directories and files anyway.
- What file modes should we use?

Since we can reconstruct the path at any time, simply do so instead
of explicitly duplicating and storing it.

We don't do any directory operations aftwerwards, so we can just
chdir into the input directory.

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.

It only contains helpers for _common_ stuff for all the utilities. The
actual high level stuff has been moved to libsquashfs a while ago.

This signature was forgotten in commit d758950ac88c (Replace
fstree/sqfshelper xattr code with sqfs_xattr_writer_t) causing the build
to fail without SELinux enabled.

The file_info_t no longer stores the size or other such information,
so there is no need to do a stat on the input file. This also means
that gensquashfs no longer needs to change the working directory when
using the function.

This commit splits the SELinux relabeling function up into 3 parts:
- open the label file
- apply relabeling rules to a given file
- close the label file
The relabeling is done while building the tree (if reading from an
input directory) or in a post process step if reading from a desription
file.

Same rational as for the dir-scanner code: It's actually the only user and
it is going to get a lot closer integerated with libsquashfs.

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.

- The write_data_from_file function no longer needs the block size
- Also remove the old data writer flags, pass the flags argument
directly to the begin-file function.

- Move the statstics hooks to the rest of the statistics code
- Used the new data writer directly in gensquashfs & tar2sqfs
- Demote what is left to a helper function for processing an
input file and submitting it to the new data writer

- file list is no longer needed for statistics
- the size field in the directory info structure is no longer in use
- sqfs2tar, rdsquashfs and sqfsdiff no longer depend on libfstree.a

First, this commit moves the create-blocks-from-fd function over to
libsquashfs and ports it to work on an sqfs_file_t instead.
Second, the function in the data_writer that reads from a file descriptor
is adjusted to use an sqfs_file_t instead.
Finally, the tools that use it have to be adjusted accordingly.

As a side effect, this requires the data writer to keep track of
statistics.

This should make it easier to use libsquashfs with custom setups that
embedd a squashfs image inside something else. Also, it should make
it easier to port to non unix-like platforms.

This commit moves stuff like printing help text, command line option
processing and enumerating available processors on stdout out of
the generic compressor code.
The option string is replaced with a structure that directly exposese
the tweakable parameters for all compressors. A function for parsing
the command line arguments into this structure is added in sqfshelper.

The idea is to make libsquashfs.a independend of libfstree.a, so it becomes
a general purpose squashfs manipulation library. All the high level glue code
for libfstree.a and utilites that are overly specific with to tools are moved
to a seperate librarby.
This commit makes the first step by moving the stuff with dependencies on
libfstree to a seperate library.

This change removes the need for passing a list of files around for
deduplication. Also the deduplication code no longer needs to worry
about order, since the file being deduplicated is only added after
deduplication is done.
