fix test-serve breakage for other hostnames

util: test fileno() availability in win32 set_binary() Fix suggested by Alexander Belchenko <bialix@ukr.net>

tests: fix repeatability for test-filebranch with dirstate granularity

tests: remove some unnecessary sleeps

dirstate: refactor granularity code, add a test - rename option dirstate.granularity - move option reading into .write() - add a simple test

dirstate: ignore stat data for files that were updated too recently This should fix the race where hg commit foo <change foo without changing its size> happens in the same second and status is fooled into thinking foo is clean. A configuration item is used to determine the timeout, since different filesystems may have different requirements (I think VFAT needs 3s, while most Unix filesystems are fine with 1s).

pager: remove pager code from core

pager: further simplify code, clean up comments

Use the pager given by the environment to display long output Unix systems usually have a PAGER environment variable set. If it is set, mercurial will use the pager application to display output. Two configuration variables are available to influence the behaviour of the pager: pager.application sets the application to be used pager.quiet silences Broken Pipe errors that might occur when the user quits the pager before mercurial finished to write the output

hgk: don't exit if mercurial commands only print warnings
