avoid a traceback with hg branch newbranch; hg up

Fix handling of paths when run outside the repo. The main problem was that dirstate.getcwd() returned just "", which was interpreted as "we're at the repo root". It now returns an absolute path. The util.pathto function was also changed to deal with the "cwd is an absolute path" case.

pass repo.root to util.pathto() in preparation for the next patch

hgweb: handle IOErrors and OSErrors during unbundle This allows the client to display a reasonable message to the user (e.g. "Permission denied: .hg/lock"), instead of the current "<url> does not appear to be an hg repository".

hgweb.unbundle: call req.httphdr only after the last possible call to bail

Work around a urllib2 bug in Python < 2.4.2 When urllib2 base64-encodes the password needed for the Proxy-authorization header, it forgets to remove the trailing "\n". Later, a "\r\n" sequence is appended to every header, as required by the standard. Some proxies interpret the resulting "\n\r\n" sequence in the same way as "\r\n\r\n": end of headers. This usually doesn't cause trouble for this request, but when the proxy tries to read the next one, it thinks the request starts with some garbage and returns a "400 - Bad Request" error.
