termios: Consolidate struct termios

This patch consolidates the struct termios definition on its own header
and adds arch-defined ones for ABIs that deviate from generic
implementation. They are:

  - alpha which has a slight different layout than generic one (c_cc
    field is defined prior c_line).

  - sparc and mips which do not have the c_ispeed/c_ospeed fields.

No semantic change is expected, checked on a build against x86_64-linux-gnu,
alpha-linux-gnu, mips64-linux-gnu, and sparc64-linux-gnu.
