EHLO must reset the transaction
RFC5321 §4.1.4 states that an EHLO command MAY be issued by a client
later in the session and, if it's acceptable, it MUST clear all buffers
and reset the state exactly as if a RSET command was issued.

error with EINVAL if open(2) is called with both O_CREAT and O_DIRECTORY
Before this change:
If no file or directory matching the last component of a path existed.
A regular file was created, an error was returned and errno set to ENOTDIR.
If a regular file matching the last component of a path existed,
an error was returned and errno set to ENOTDIR.
If a directory matching the last component of a path existed,
it was opened without error.
One possible reading of POSIX is that O_CREAT | O_DIRECTORY is a valid way
to get a file descriptor for an existing directory. In practice it isn't
used and the combination of O_CREAT and O_DIRECTORY has returned an error
on NetBSD since 2010 and Linux since 2023.

Add support for the RK3528 variant. To make things easier to follow,
pull the hardware differences out into a per-variant structure containing
the different parameters we have to program.
tested on 3528 (radxa e20c), 3568 (nanopi r5s), 3588 (nanopi r6c)

Respect DEBUG so we can build perl with debug symbols
Adding -DEBUGGING in CONFIGURE_ARGS activates debug code,
-DEBUGGING=-g passes -g in CFLAGS (only -g is supported),
and -DEBUGGING=both does... both. This is a bit confusing.
IMO DEBUG=-g should only add -g and disable executable stripping, but
not change the code that is built. So use -Doptimize which lets us pass
arbitrary compiler flags (eg -g3), just like DEBUG does in our system
Makefiles.
