Subject: 28.0.50; Require Emacs 26.1, nor Emacs 26.3, in project.el and xref.el core packages

Hi,

Some time ago, I made these two files into GNU ELPA "core" packages, and
I chose Emacs 26.3 as the minimum required version.  That was rather
arbitrary and I should have selected Emacs 26.1 instead.

This is because these packages are required by Eglot, which for now, is
specified to work in Emacs 26.1.

Recently an Eglot user complained that he could no longer run Eglot in
that Emacs version, stating that Emacs 26.1 is the version of Emacs
distributed with Debian stable.

So, I've (briefly) tested these two files in Emacs 26.1 and things seem
to work, so I propose the simple change in the patch after my sig.  If
no-one opposes, I'll push in few days or so.

João
