wireproto: client reactor support for receiving frames
We can now feed received frames into the client reactor and it will
validate their sanity, dispatch them appropriately.
The hacky HTTP peer has been updated to use the new code. No
existing tests changed, somewhat proving the code works as
expected.
Rudimentary unit tests for the new functionality have been
implemented.

$ hg init
$ echo a > a
$ hg ci -Ama
adding a
$ echo b > b
$ hg branch b
marked working directory as branch b
(branches are permanent and global, did you want a bookmark?)
$ hg ci -Amb
adding b
$ hg co -C 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
Fast-forward:
$ hg merge b
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
$ hg ci -Ammerge
Bogus fast-forward should fail:
$ hg merge b
abort: merging with a working directory ancestor has no effect

Even with strange revset (issue4465)
$ hg merge ::.
