Subject: Bug 62980 - matching native fonts with even :lang=en

Fix the matcher modified by 4eab908c8679a797ac7016b77a93ee41bb11b0fc
to deal with both strong and weak of FC_LANG as the same location in the score

Subject: build-chain, replace INCLUDES directive by AM_CPPFLAGS

As of automake-13.1 the INCLUDES directive is no longer supported.
An automake run will return with an error.

This changeset simply follows automake's advice to replace INCLUDES
by AM_CPPFLAGS.

Subject: Bug 63329 - make check fails: .. contents:: :depth: 2

Add back FcHashGetSHA256DigestFromFile() and fall back to it
when font isn't SFNT-based font because FT_Load_Sfnt_Table
fails with FT_Err_Invalid_Face_Handle.
