wireprotov1peer: simplify the way batchable rpcs are defined

The scheme with futures/generator is confusing due to the way
communication is done by side effects, especially with two different
"future" objects. Just returning a request and a function to read the
response is easier to understand.

There are tests failures with the largefiles extension due to it
aliasing one rpc to another one, which gets fixed in the next commit.

Windows needs ';' as a file separator in an environment variable, and MSYS
doesn't automatically convert it in every case.

#if windows
  $ path_list_var() {
  >     echo $1 | sed 's/:/;/'
  > }
#else
  $ path_list_var() {
  >     echo $1
  > }

Test config default of various types:

 {"defaultvalue": ""} for -T'json(defaultvalue)' looks weird, but that's
 how the templater works. Unknown keywords are evaluated to "".

configs should be read in lexicographical order

  $ HGRCPATH=configs hg config section.key

  $ cat > included-alias-D.rc << EOF
  > [ui]

  > EOF

Simple order checking
---------------------

If file B is read after file A, value from B overwrite value from A.

  $ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg config config-test.basic
  value-B

Ordering from include
---------------------

value from an include overwrite value defined before the include, but not the one defined after the include

  $ HGRCPATH="file-A.rc" hg config config-test.pre-include
  value-included
  $ HGRCPATH="file-A.rc" hg config config-test.post-include
  value-A

command line override
---------------------

  $ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg config config-test.basic --config config-test.basic=value-CLI
  value-CLI

Alias ordering
--------------

The official config is now `command-templates.log`, the historical
`ui.logtemplate` is a valid alternative for it.

When both are defined, The config value read the last "win", this should keep
being true if the config have other alias. In other word, the config value read
earlier will be considered "lower level" and the config read later would be
considered "higher level". And higher level values wins.

  $ HGRCPATH="file-A.rc" hg log -r .
  value-A
  $ HGRCPATH="file-B.rc" hg log -r .
  value-B
  $ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg log -r .
  value-B

Alias and include
-----------------

The pre/post include priority should also apply when tie-breaking alternatives.
See the case above for details about the two config options used.

  $ HGRCPATH="file-C.rc" hg log -r .
  value-C
  $ HGRCPATH="file-D.rc" hg log -r .
  value-included

command line override
---------------------

  $ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg log -r . --config ui.logtemplate="value-CLI\n"
  value-CLI
