Validate psmfplayer config params, reset on create.

Could fix issues if a game uses different pixel modes or more likely
different loop modes.
Fix overflow in scePsmfPlayerGetCurrent*Stream().

And clean up the returned error codes.
Make scePsmfPlayerSelect*() actually switch.

Don't have any games actually using this, so let's report too.  Audio is
falsely working when the stream isn't playable, not exactly sure the best
way to detect that.
Attempt scePsmfPlayerSelectSpecific*().

These functions seem buggy on a real PSP... and they return a weird
variety of error codes.
Decrease log level in sceUtilityNetconfUpdate

Spam in Danball Senki BOOST
Report scePauth_F7AA47F6

To make tpunix easier to debug
Add sceDisplaySetMode error code base on JPCSP
Fix some minor styling issues in PSPNetconfDialog.cpp.
Add errors for getting and changing the playmode.

And reporting.  Also, correct the default playMode for unset psmfplayers.
sceUtility: fix some typo and formatting
Enable --escape-exit for all relevant platforms. It makes PPSSPP more front-end friendly by letting escape quit the emu.
Fix Linux build.
Correct PTS reading during audio demux.
Instead of using escape only, allow anything mapped to "Pause" to exit as well.
Fix Linux build, again.
Improve scePsmfPlayer*Data() timing.

Instead of blocking, video should just return old data if called too
often.  Fixes #5910.
Change the scepauth report identifier
