ToddRK deba6720fb fsck.cramfs: fix fsck.cramfs crashes on blocksizes > 4K
fsck.cramfs crashes when extracting a cramfs image with a 16KB blocksize.
The read_buffer is hardcoded for a 4KB blocksize.  When using a blocksize
larger than 4KB, the program's code uses indexes that go past the end of the
allocated space for the read_buffer and this causes the crash.

The following changes fix the problem for me in the latest 2.36.1 release of
fsck.cramfs.c.  However there are hardcoded values of 4096 in the code that
might cause problems under other circumstances and I have not attempted to
fix those.

 SCM (Source Code Management) Repository:

    Primary repository:
	  git clone git://git.kernel.org/pub/scm/utils/util-linux/util-linux.git

    Backup repository:
	  git clone git://github.com/karelzak/util-linux.git

    Web interfaces:
	  http://git.kernel.org/cgit/utils/util-linux/util-linux.git
	  https://github.com/karelzak/util-linux

      Note: the GitHub repository may contain temporary development branches too.

      The kernel.org repository contains master (current development) and stable/*
      (maintenance) branches only. All master or stable/* changes are always pushed
      to both repositories at the same time.

    Repository Branches: 'git branch -a'
	  master branch
	   - current development
	   - the source for stable releases when deemed ready.
	   - day-to-day status is: 'it works for me'. This means that its
	     normal state is useful but not well tested.
	   - long-term development or invasive changes in active development are
	     forked into separate 'topic' branches from the tip of 'master'.

	  stable/ branches
	   - public releases
	   - branch name: stable/v<major>.<minor>.
	   - created from the 'master' branch after two or more release
	     candidates and the final public release. This means that the stable
	     releases are committed, tagged, and reachable in 'master'.
	   - these branches then become forked development branches. This means
	     that any changes made to them diverge from the 'master' branch.
	   - maintenance releases are part of, and belong to, their respective
	     stable branch. As such, they are tags(<major>.<minor>.<maint>) and
	     not branches of their own. They are not part of, visible in, or
	     have anything to do with the 'master' development branch. In git
	     terminology: maintenance releases are not reachable from 'master'.
	   - when initially cloned (as with the 'git clone' command given above)
	     these branches are created as 'remote tracking branches' and are
	     only visible by using the -a or -r options to 'git branch'. To
	     create a local branch use the desired tag with this command:
	     'git checkout -b v2.29.2 v2.29.2'

    Tags: 'git tag'
	   - a new tag object is created for every release.
	   - tag name: v<version>.
	   - all tags are signed by the maintainer's PGP key.

    Known Bugs:
	- don't use tag v2.13.1 (created and published by mistake),
	  use v2.13.1-REAL instead.

WORKFLOW EXAMPLE:

 1) development (branch: <master>)

 2) master release (tags: v2.29-rc1, v2.29-rc2, v2.29, branch: <master>)

 3) development (work on v2.30, branch: <master>)

 4) fork -- create a new branch <stable/v2.29> based on tag v2.29

     4a) new patches or cherry-pick patches from <master> (branch: <stable/v2.29>)

     4b) stable release (tag: v2.29.1, branch: <stable/v2.29>)

     4c) more patches; another release (tag: v2.29.2, branch: <stable/v2.29>)

 5) master release v2.30 (branch: <master>)
    ...

where 3) and 4) happen simultaneously.
