Fix two small bugs in tcsetattr().
- According to POSIX, tcsetattr() must not fail when any of the bits in
the structure are unsupported, but it must leave the unsupported flags
alone.
- The CIGNORE flag (set by TCSASOFT, extension) was not cleared from
c_cflag, which means using it would cause it to be applied during its
entire lifespan. Eventually make sure we clear the flag.
I don't really like CIGNORE, but I think we must keep it alive right
now. With our new TTY layer, we don't actually need this mechanism,
because if you leave c_cflag, c_ispeed and c_ospeed alone, we won't make
a call into the device driver anyway.
