capmt: support for OSCam; fixes

[manio]

Hi!
Finaly - my oscam support is done :)
Additional two fixes for the capmt also in this PR.

Last commit seems very big, but changes are small, you can see with ignoring whitespaces:

git diff b90d7d1^ -b

I have oscam but currently using the code word client setup, if you let me know how to move over I can test

[manio]

@xxxnelly just add this section to oscam.conf:

[dvbapi]
enabled                       = 1
au                            = 1
boxtype                       = pc
user                          = tvh
pmt_mode                      = 4
request_mode                  = 1

and to oscam.user:

[account]
user = tvh
group = 1
uniq = 0
au = 1

Disable CWC entries, and add an entry to capmt with socket /tmp/camd.socket, "oscam mode" enabled
