GPE address book support: cfg option, drop SQLite 2
Rename the confusing config option to enable GPE address book support, and drop support for ancient SQLite 2 libs. See issue #93 (closed) for further discussion.
Details:
- README.md, configure.ac, meson.build, meson_options.txt: rename configure option from “--with-sqlite” to “--with-gpe”, do not try to detect sqlite v. 2, rename #define from HAVE_SQLITE to HAVE_GPE
- libbalsa/address-book-gpe.c: remove conditional code for sqlite v. 2
- libbalsa/address-book-gpe.h, libbalsa/libbalsa.[ch], src/ab-main.c, src/ab-window.c, src/address-book-config.c, src/pref-manager.c: rename #define from HAVE_SQLITE to HAVE_GPE
