2008-05-08vt: fix canonical input in UTF-8 modeSamuel Thibault
For e.g. proper TTY canonical support, IUTF8 termios flag has to be set as appropriate. Linux used to not care about setting that flag for VT TTYs. This patch fixes that by activating it according to the current mode of the VT, and sets the default value according to the vt.default_utf8 parameter.

2008-05-01remove div_long_long_remRoman Zippel
x86 is the only arch right now, which provides an optimized for div_long_long_rem and it has the downside that one has to be very careful that the divide doesn't overflow. The API is a little akward, as the arguments for the unsigned divide are signed. The signed version also doesn't handle a negative divisor and produces worse code on 64bit archs. There is little incentive to keep this API alive, so this converts the few users to the new API.
