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.
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".
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.
