6a575b8900 use correct type for sizeof
**L would have worked well too.  Depending on the distribution sizeof *L
may return 8 instead of 4. **L is preferable, but since we don't expect
this datatype to change very often, sizeof int is less subtle and easier
to understand.

19c31231fa ui-ssdiff.c: correct length check for LCS table
Each individual string may be too long for its respective
dimension of the LCS table.

e19f7d7180 ui-ssdiff: move LCS table away from the stack
Printing deferred line changes for files containing long lines would
cause a segfault.

- limit LCS table size: 128x128.
- move LCS table to global context: avoid allocating/freeing memory
  for every deferred line change.

735e15e38a In side-by-side diff, add support for marking individual characters.
Refuses to do so if the left hand side of the diff has different amount of
differing lines to the right hand side to avoid confusion.

Note that I use the naive dynamic programming approach for calculating the
longest common subsequence. We could probably be more efficient by using a
better algorithm. The LCS calculating function is O(n*m) and uses up n*m
amount of memory too (so if we we compare two strings of length 100, I use
an array of 10000 for calculating the LCS). Might want to not calculate LCS
if the length of the line is too large.

4a198e4b8e Fixed side-by-side diff bugs related to binary diff and more.
The fixed bugs:

 * "Binary files differ" did not show up either in unidiff or
   side-by-side-diff.
 * Subproject diffs did not work for side-by-side diffs.
 * The ssdiff link on diff pages did not conserve the path.

207cc34711 Polishing of how the side-by-side diff looks.
Aligned all different files, so that all side-by-side tables look
the same. Also made sure that the tables take up the whole browser
width.

Also various changes to the css to make things easier on the eye.

40e174d536 First version of side-by-side diff.
This constitutes the first prototype of a side-by-side diff. It is not
possible to switch between unidiff and side-by-side diff at all at this
stage.
