Andrew Bettison 3ffa4b10af Add Swift keyring client API with tests
Add a swift-client-api subdirectory containing a Swift source package
and a Makefile.in that compiles it into the "ServalClient" Swift module
using the Swift package manager.  The Swift API contains the following
classes:

- ServalKeyring provides the operations: add, remove, set, list
- AbstractId and its specialisation SubscriberId, already in near-final
  form, are data types for SID and the like
- ServalRestfulClient (internal) uses an HTTP client to access the
  Serval DNA RESTful interface

Improve the REST /keyring/set operation to only alter the DID or Name if
the corresponding query parameter is supplied.  Modify the internal
keyring_set_did() function to only assign the DID or Name if the
corresponding parameter is not a null pointer.

The configure script ensures that the Swift build target version is
10.10 or later when compiling for Mac OS-X, so that the package manager
will succeed.

Add autoconf macros for the Swift package manager.

# Serval Project Swift language support
#
# SYNOPSIS
#
# AX_PROG_SWIFT_PACKAGE_WORKS
#
# DESCRIPTION
#
# AX_PROG_SWIFT_BUILD_WORKS tests whether the Swift package manager "package"
# command works.
#
# Requires the SWIFT shell variable to contain the path of the Swift package
# manager executable (not the Swift compiler!), either relative to $PATH or
# absolute; this will usually be just "swift".
#
# Sets the SWIFT_PACKAGE variable to the command to invoke the manage-package
# command, usually "swift package".
#
# To force a specific swift executable, either:
#
# - in configure.ac, set SWIFT=yourswift before calling
# AX_PROG_SWIFT_PACKAGE_MANAGER, or
#
# - before invoking ./configure, export SWIFT=yourswift
