test-hgrc: do not print ui.plain() flag at uisetup() This makes the test pass with chg. Since uisetup() is run per process, "hg showconfig" does not always call uisetup().

tests: make config/help tests pass even if chgserver extension is loaded It isn't important for these tests if "extensions.chgserver=" is set or not. So let's make them ignore such lines.

setup: alphabetize hgext packages

remove: add progress support

remove: queue warnings until after status messages (issue5140) (API) Before this change, warnings were interspersed with (and easily drowned out by) status messages. API: abstractsubrepo.removefiles has an extra argument warnings, into which callees should append their warnings. Note: Callees should not assume that there will be items in the list, today, I'm lazily including any other subrepos warnings, but that may change. cmdutil.remove has an extra optional argument warnings, into which it will place warnings. If warnings is omitted, warnings will be reported via ui.warn() as before this change (albeit, after any status messages).

tests: include progress for test-remove

chg: allows default hg path to be overridden Before this patch, chg will fall back to "hg" if neither CHGHG nor HG are set. This may have trouble if the "hg" in PATH is not compatible with chg, which can happen, for example, an old hg is installed in a virtualenv. Since it's very hard to do a quick hg version check from chg, after discussion in IRC with smf and marmoute, the quickest solution is to build a package with a hardcoded absolute hg path in chg. This patch makes it possible by adding a C macro HGPATH.

chg: define PRINTF_FORMAT_ for non gnu C compiler Before this patch, if __GNUC__ is not defined, PRINTF_FORMAT_ will not be defined and will cause compilation error. This patch solves the issue by making sure PRINTF_FORMAT_ is defined. It allows chg to be compiled with tcc (http://bellard.org/tcc/) by: tcc -o chg *.c

chgserver: drop bundle.mainreporoot config Before this patch, although chgserver drops repo object by setting it to None, there is another side effect loading a repo: setting bundle.mainreporoot. This patch explicitly sets it to empty to undo the side effect. It will make chg pass test-strip.t.

chgserver: drop old hack to recreate ui on HGPLAIN change It's been superseded by config/env hash. A log message is simplified as we no longer need a diff of environment variables. Also, _loadnewui() is changed to require args since it can't copy old --config values without args.
