freetype/fontconfig support for fontsrv

Very cool stuff. Thank you.

You should remove heading tabs in empty lines in x11.c.

Thanks, I've updated. There are some minor issues though:
With some fonts, when typing in Hebrew letters I'm getting:
stringwidth: bad character set for rune 0x0000 in 9/font/Source Sans
Pro/12a/font

without the cursor advancing, while other fonts do not generate the message and
the cursor advances (but no rectangle is drawn).
Also somewhat related I've been getting linker error from mempoly.

File src/cmd/devdraw/mkwsysrules.sh (right):

src/cmd/devdraw/mkwsysrules.sh:51: echo 'LDFLAGS=$LDFLAGS -lfontconfig
-lfreetype -lz'
I am a little worried about requiring these for the X build. Can we move these
changes into the fontsrv mkfile?

I've added a freetyperules.sh script instead.
Is it alright I'm hardcoding dpi to be 96 ? I can calculate it using Xrander but
on my Ubuntu the calculated dpi is 131 while Xft and xorg report 96..

I expect this to break for some people, but we can deal with that when
it happens.
