[PATCH 00/10] Prepare for advertised remotes auto-configure via URL allowlist

[Christian Couder <christian.couder@gmail.com>]

Recently, I sent a 16 patch long series that makes it possible for
promisor remotes advertised through the "promisor-remote" protocol
capability to be auto-configured on the client side via a URL
allowlist configured using a new `promisor.acceptFromServerUrl`
configuration variable:

I got the suggestion to split the 16 patches series into two smaller
series, starting with a preparatory series. So here is this
preparatory series. It's a mix of mostly small fixes, refactorings and
cleanups.

High level description of the patches
=====================================

 - Patches 1-4/10 are fixes:

   - Patch 1/10 is the most significant. The others are relatively
     small.
     
   - Patch 4/10 is the only new in this series (while all the others
     were in the previous series). It prepares for Patch 5/10.

 - Patches 5-10/10 are refactorings and cleanups:

   - Patches 5-7/10 are relatively small independents cleanups or
     refactorings.

   - Patches 8-9/10 are related refactorings simplifying the data
     structures used in filter_promisor_remote() and
     promisor_remote_reply().

   - Patch 10/10 is cleaning up the 'file://' URIs with absolute paths
     in the test script.

CI tests
========

They all pass, see:

Range-diff
==========

Sorry, no range-diff as I don't think it would be quite useful because
the number and order of commits has changed a lot.

Christian Couder (10):
  promisor-remote: try accepted remotes before others in get_direct()
  promisor-remote: pass config entry to all_fields_match() directly
  promisor-remote: clarify that a remote is ignored

  promisor-remote: refactor should_accept_remote() control flow
  promisor-remote: refactor has_control_char()
  promisor-remote: refactor accept_from_server()
