hgweb: reuse body file object when hgwebdir calls hgweb (issue5851)
An unintended side-effect of f0a851542a05 was that the request body
file object (which uses a util.cappedreader) was constructed twice
when hgwebdir called into hgweb. Since we attempt to read all remaining
data from this file object when Content-Length is defined and since there
were two instances of this object and the client supplied no additional
data to read, this resulted in deadlock.
The fix implemented in this commit is to reuse the request body file
object when it is passed from hgwebdir to hgweb.
A test demonstrating `hg clone` and `hg push` via hgwebdir has been
added. Without this patch, the test hangs when doing `hg clone`.
Surprisingly, this must mean that we have effectively no test coverage
of the wire protocol when run via hgwebdir.
