fix compiler warnings in hurd/console-client

console-client: Fix several compiler warnings.

* console-client/bdf.c: Use size_t instead of int.
* console-client/driver.c: Remove unused variable errstring.
* console-client/pc-kbd.c: Cast sc to scancode_x1 before comparing with enum
values.
* console-client/vga-dynacolor.h: Use an explicit if in reference counting.
* console-client/vga-dynafont.c: Use usigned char for bitmaps.
* console-client/vga-support.c: Use unsigned char instead of char.
* console-client/vga-support.h: Likewise.
* console-client/vga.c: Use conchar_attr_equal instead of casting structures to
integers.
* hurd/console.h: Add conchar_attr_equal to compare conchar_attr_t structures.
