server: Fix segfault in com_sender().
Commit
1709cc8f (server: Convert non-afs commands to lopsub) from
one year ago dropped the terminating NULL pointer from the array
of sender commands, presumably because the array size is declared
as the NUM_SENDER_CMDS enum constant, and this constant can be used
to iterate over all sender subcommands.
However, the loop in check_sender_args() of command.c does not
terminate the loop after NUM_SENDER_CMDS elements but only when it
encounters a NULL pointer. Hence, without the terminating NULL, the
code reads beyond the end of the array. The resulting invalid memory
access causes the command handler process to segfault.
Fix this by changing the termination condition of the loop to check
the loop variable against NUM_SENDER_CMDS.

vss: Avoid use after free in vss_send().
In vss_send() we increment the current slice number for the fec
client after fc->send_fec() has sent a slice. This results in a use
after free in case of a write error because ->send_fec() frees the
fec client structure on write errors. Valgrind complains about this
with the splat below.
To avoid this, the fc pointer must not be dereferenced after
->send_fec() has been called. This patch increases the current slice
number *before* the call to ->send_fec(). This works because the fec
clients do not care about this number.
The bug was introduced eight years ago in commit
625c5cd (Add forward
error correction code to the udp sender/receiver).

manual: Omit level 3 headers from table of contents.
The table of contents was rather large because it contained too much
detail. This commit converts all level 3 headings to inline html which
has no visible effect except that the headings no longer appear in
the table of contents.

manual: Combine overview.pdf and the user manual.
The figures of the overview.pdf file look rather odd although they
used to look better when they were created four years ago. Apparently,
the dia command line tool which creates the pdf from the .dia source
file has changed and now messes up the lines which connect the parts
of the figure.
This commit re-implements four out of the five figures of the overview
file as ascii art in manual.md, removes overview.dia, and modifies
the documentation web page to no longer refer to the dia version.
The text of the overview file has been merged with the manual and
got improved a bit.

doxygen: Avoid segfault.
After an upgrade to Ubuntu-16.04, the new doxygen version 1.8.11
started to segfault. It turned out that this can be circumvented
by disabling USE_HTAGS so that doxygen will use its built-in source
browser instead of the htags tool of GNU global.
However, the html which is generated by the built-in source browser
the source code is unreadable because leading tab characters are not
shown, so indentation is messed up.
This patch deactivates the source browser for now, getting rid of
all source code in the generated output.
