Subject: [PATCH] Change event for tabline autoshow

Use TabNew/TabClosed for the "autoshow" event when tabline is used only
for tabs (show_buffers==0).  This fixes case of visible tabline when
tab_min_count == 2 and user executes ':tabonly' command - the tabline
should disappear but there is no TabEnter event triggered in this case.

Closes #2389
