[PATCH 0/2] Add support for Guile 3.0 and 2.2

[Ludovic Courtès]

Hello,

This is a long overdue update to the Guile bindings to support versions
2.2 (legacy) and 3.0 (current stable), in addition to the old 2.0.

For the record, the last 2.0 release was made in February 2017, but I
think keeping 2.0 support for a while will make the transition smoother.

Most of the work is about updating code that uses Guile’s I/O ports to
the new API that was introduced in Guile 2.2.  The new API leads to more
concise and less error-prone code but of course, since we’re also keeping
the 2.0 version, we’d only adding code at this point.

Tested with Guile 3.0.2, 2.2.7, and 2.0.14 on x86_64-linux-gnu (GNU Guix).
Specifically, this passes for all three versions:

  make check -C gdb TESTS=gdb.guile/*.exp

Let me know what you think!

Thanks,
Ludo’.
