Most casts where PVS warns for V1028 aren't added to prevent overflows
in the first place, but to avoid other warnings, like printf argument or
-Wconversion warnings. PVS/V1028 is more annoying than useful.
* fix(PVS/V002): disable rule completely
V002: "Some diagnostic messages may contain incorrect line number in
this file." This particular check seems unreliable. It says on their
website https://pvs-studio.com/en/docs/warnings/v002/ that this warning
occurs when there are multiline pragmas, but there are none in
extmark.c.
* fix(PVS/V756): ignore "counter is not used inside a nested loop" warning
The nested loop starts with "AutoCmd *ac = ap->cmds" so "ap" is
definitely used.
* fix(PVS/V560): disable "a part of conditional expression is always true"
* fix(PVS/V614): potentially uninitialized variable 'blen' used
PVS is worried about typos. Now we need it to stop worrying...
Disable these checks entirely, they are all false positives.

Reverts previous experiment. PVS root is working correctly, one can
observe this in the PVS-studio.err file, for example:
/usr/local/clang-7.0.0/lib/clang/7.0.0/include/stddef.h:51:1: warning: V677 ...
/usr/local/clang-7.0.0/lib/clang/7.0.0/include/stddef.h:132:1: warning: V677 ...
./src/nvim/fileio.c:1382:1: warning: V1026 ...
./src/nvim/fileio.c:1388:1: warning: V1026 ...
The "./src/nvim/…" paths are correctly rooted, yet PVS somehow still
thinks it should analyze "/usr/local/clang-7.0.0/…".

plog-converter behaviour is not the best one when creating fullhtml report and
directory already exists: it puts report inside an existing directory. Not sure
what exactly it does if inside exists as well, but if I am not mistaking report
will not be created.
The hardcoded URL breaks very often, this confuses people.
Instead, auto-detect if no URL is provided.
Also auto-detect if the script is invoked with no arguments.
Needed as argument list is growing large and I absolutely do not find short
options provided by getopts being particularly readable for unfamiliar commands.
