wip/thunderbird

[Havard Eidnes <he%NetBSD.org@localhost>]

Hi,

I have taken a first stab at updating mail/thunderbird, and my
draft (which still doesn't build), is now in wip/thunderbird.

The reason I started down this path is that the existing
mail/thunderbird did not want to build with rust 1.71.1 (also
from pkgsrc-wip) installed; the build errors out on

error[E0277]: cannot multiply `u64` by `NonZeroU8`
    --> /usr/pkgsrc/mail/thunderbird/work/thunderbird-102.8.0/third_party/rust/mp4parse/src/lib.rs:3188:62

with a longer error message at that point.

The setup I now have in wip/thunderbird is thunderbird version
115.1.1, and the build managed to progress for about one hour
wallclock time (csh's time said "32293.502u 2835.343s 51:17.63
1141.4%") on a 16-core amd64 system (so that one can "adjust
expectations" if trying to build this) before bombing out with

ld: ../../toolkit/library/build/libxul.so: undefined reference to `malloc_usable_size

More details about my investigations about this exact error in
wip/thunderbird/TODO.

I'll have to admit that I'm stumped at this point, and have
therefore checkpointed what I had done so far to wip/thunderbird,
and solicit assistance to get this updated.

Regards,

- Håvard
