Bug#989891: unblock: libgee-0.8/0.20.4-1

[Graham Inggs <ginggs@debian.org>]

Package: release.debian.org
Severity: normal
User: release.debian.org@packages.debian.org
Usertags: unblock

Please unblock package libgee-0.8

[ Reason ]
libgee-0.8/0.20.3-1 in testing currently FTBFS against the current
valac (#988020)

[ Impact ]
libgee-0.8 is not able to be updated in testing

[ Tests ]
libgee-0.8 has no autopkgtests, but a test suite is run during the build

[ Risks ]
Low, the changes in upstream 0.20.4 seem to be documentation fixes and
compatibility with the new valac only.  0.20.4-1 has been in unstable
for 3 months, and was part of the Ubuntu 21.04 release with no new
bugs filed.

[ Checklist ]
  [ ] all changes are documented in the d/changelog
  [x] I reviewed all changes and I approve them
  [ ] attach debdiff against the package in testing

[ Other info ]
The debdiff is very large and contains numerous generated .c files.
As can be seen in upstream's recent commits [1], the only changes
since 0.20.3 were:

* Various English and typo fixes in the documentation [2]
* Replace Memory.dup() with GLib.malloc() and Memory.copy() [3]
* Remove invalid usage of type-argument for
Gee.Future.SourceFuncArrayElement [4]
* Release 0.20.4 [5]
