debugcommands: support sending HTTP requests with debugwireproto

We implement an action that can issue an HTTP request. We can define
headers via arguments and specify a file to use for the HTTP request
body.

The request uses the HTTP peer's opener, which is already configured
for auth, etc. This is both good and bad. Good in that we get some
nice behavior out of the box. Bad in that some HTTP request headers
are added automatically.

Test exit code when no config matches

  $ hg config Section.idontexist
  [1]

sub-options in [paths] aren't expanded

  $ cat > .hg/hgrc << EOF

  $ hg showconfig paths
  paths.foo:suboption=~/foo

edit failure

  $ HGEDITOR=false hg config --edit
  abort: edit failed: false exited with status 1
  [255]

config affected by environment variables

  $ EDITOR=e1 VISUAL=e2 hg config --debug | grep 'ui\.editor'
  $VISUAL: ui.editor=e2

  $ VISUAL=e2 hg config --debug --config ui.editor=e3 | grep 'ui\.editor'
  --config: ui.editor=e3

  $ PAGER=p1 hg config --debug | grep 'pager\.pager'
  $PAGER: pager.pager=p1

  $ PAGER=p1 hg config --debug --config pager.pager=p2 | grep 'pager\.pager'
  --config: pager.pager=p2

verify that aliases are evaluated as well

  $ hg init aliastest
  $ cd aliastest
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..

alias has lower priority

  $ hg init aliaspriority
  $ cd aliaspriority
  $ cat > .hg/hgrc << EOF
  > [ui]
  > user = alias user
  > username = repo user
  > EOF
  $ touch index
  $ unset HGUSER
  $ hg ci -Am test
  adding index
  $ hg log --template '{author}\n'
  repo user
  $ cd ..
