vt: redefine world of cursor macros
The cursor code used to use magic constants, ANDs, ORs, and some macros.
Redefine all this to make some sense.
In particular:
* Drop CUR_DEFAULT, which is CUR_UNDERLINE. CUR_DEFAULT was used only
for cur_default variable initialization, so use CUR_UNDERLINE there to
make obvious what's the default.
* Drop CUR_HWMASK. Instead, define CUR_SIZE() which explains it more.
And use it all over the places.
* Define few more masks and bits which will be used in next patches
instead of magic constants.
* Define CUR_MAKE to build up cursor value.
