wireproto: require POST for all HTTPv2 requests

Wire protocol version 1 transfers argument data via request
headers by default. This has historically caused problems because
servers institute limits on the length of individual HTTP headers
as well as the total size of all request headers. Mercurial servers
can advertise the maximum length of an individual header. But
there's no guarantee any intermediate HTTP agents will accept
headers up to that length.

In the existing wire protocol, server operators typically also
key off the HTTP request method to implement authentication.
For example, GET requests translate to read-only requests and
can be allowed. But read-write commands must use POST and require
authentication. This has typically worked because the only wire
protocol commands that use POST modify the repo (e.g. the
"unbundle" command).

There is an experimental feature to enable clients to transmit
argument data via POST request bodies. This is technically a
better and more robust solution. But we can't enable it by default
because of servers assuming POST means write access.

In version 2 of the wire protocol, the permissions of a request
are encoded in the URL. And with it being a new protocol in a new
URL space, we're not constrained by backwards compatibility
requirements.

This commit adopts the technically superior mechanism of using
HTTP request bodies to send argument data by requiring POST for
all commands. Strictly speaking, it may be possible to send
request bodies on GET requests. But my experience is that not all
HTTP stacks support this. POST pretty much always works. Using POST
for read-only operations does sacrifice some RESTful design
purity. But this API cares about practicality, not about being
in Roy T. Fielding's REST ivory tower.

There's a chance we may relax this restriction in the future. But
for now, I want to see how far we can get with a POST only API.

== literals ==

The fully minimized form is the most convenient form:

In the partially minimized form a paragraph simply ends with
space-double-colon.

  long un-wrapped line in a literal block
  \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

  This literal block is started with '::',
    the so-called expanded form. The paragraph

== lists ==
60 column format:
----------------------------------------------------------------------
- This is the first list item.

  Second paragraph in the first list item.

- List items need not be separated by a blank line.
- And will be rendered without one in any case.

We can have indented lists:

  - This is an indented list item
  - Another indented list item:

      - A literal block in the middle
            of an indented list.

      (The above is not a list item since we are in the literal block.)

  Literal block with no indentation (apart from
  the two spaces added to all literal blocks).

1. This is an enumerated list (first item).
2. Continuing with the second item.
(1) foo
(2) bar
1) Another
2) List

Line blocks are also a form of list:

This is the first line. The line continues here.
This is the second line.

Bullet lists are also detected:

 -I --include         an option with both a short option and
                      a long option
    --all             Output all.
    --both            Output both (this description is quite
                      long).
