If no number is present use `Anonymous caller` instead of an
empty label in the call history.

See: #144

* src/calls-manager.h: Add lookup function to header
* src/calls-manager.c: Implement lookup function to be used for the call
  history, call notifier and call display
* src/calls-call-holder.c: Use calls_manager_get_contact_name ()
* src/calls-notifier.c: Use calls_manager_get_contact_name ()

Since passing a CallsContacts pointer down to every class it needs, started to
become laborous - especially since the intermediates classes don't need
the reference themselves - it was made a singleton

* src/calls-contacts.c: Added calls_contacts_get_default () function and
  removed calls_contacts_new ()
* src/calls-contacts.h: Added _get_default () prototype and removed the
  _new () prototype
* src/calls-application.c: Use calls_contacts_get_default () now
* src/calls-history-box.c: Removed self->contacts completely
* src/calls-history-box.h: Got rid of CallsContacts argument in _new()
* src/calls-main-window.c: Removed self->contacts completely
* src/calls-main-window.h: Got rid of CallsContacts argument in _new()
* src/calls-call-record-row.c: Use calls_contacts_get_default () now
* src/calls-call-record-row.h: Got rid of CallsContacts argument in
  _new()
* src/calls-call-holder.c: Use calls_contacts_get_default () now
* src/calls-call-holder.h: Got rid of CallsContac...

* src/ui/call-record-row.ui: Add menu, GtkPopover. Surround existing
  elements with GtkEventBox to capture longpress/rightclicks
* src/calls-call-record-row.c: Provide functions emiting "call-delete"
  signal, add widgets from ui file
* src/calls-record.c: Add "call-delete" signal
* src/calls-history-box.c: Add callback for "call-delete" signal
* src/calls-record-store.c: Add callback for "call-delete" signal
* src/util.c: Add convenience function calls_find_in_store for finding
  items in ListModel
* src/util.h: Add declaration of calls_find_in_store

Closes: #153

Otherwise this can trigger test failures. Similar to what we
did in libhandy.

Fixes errors like:
---
G_DEBUG='gc-friendly,fatal-warnings' G_TEST_BUILDDIR='/home/purism/builds/calls/_build/tests' PYTHONDONTWRITEBYTECODE='yes' MALLOC_CHECK_='2' GSETTINGS_BACKEND='memory' G_TEST_SRCDIR='/home/purism/builds/calls/tests' /home/purism/builds/calls/_build/tests/manager
--- stderr ---

(/home/purism/builds/calls/_build/tests/manager:10212): dbind-WARNING **: 12:01:50.237: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
-------

This triggers e.g. haptic feeback as well and can later on be used
for LED feedback.

We can drop the audio theme setting completely since feedbackd picks up
the global GNOME setting.

Since feedbackd currently does not cancel gsound's via a cancellable
this might make the phone ring a bit too long atm but that will be fixed
on the feedbackd side
(Librem5/feedbackd#10)

This avoids deprecation warnings due to GTimeVal used in
libebook-contacts.h

See https://tecnocode.co.uk/2019/08/24/gtimeval-deprecation-in-glib-2-61-2/

It's already fixed in newer eds so we can drop
this once we move to a newer stack.

calls_contacts_lookup_phone_number is transfer-none

This makes sure we have clear ownership rules

See https://wiki.gnome.org/Design/OS/Typography

program-name will be retrieved with g_get_application_name().
Let’s not do it explicitly so that there is one less string
to translate

Update the pot file after marking many strings as not needing
translation.

They're never used anywhere.

Closes: #155, #121

They're not meant to be translated

This makes correct taging so much simpler

* meson_options.txt: Added option librem5-hack, defaults to true
* src/meson.build: Added conditional define USE_UGLY_CODE which will be
  set when librem5-hack option is used
* src/calls-call-display.c: ifdef'ed ugly_hacks call

Adust debian/copyright accordingly.
