AM_CFLAGS are set by the recursive make, but it's CFLAGS
which we need to carry over.

A follow-up issue has been reported in #13:

Assert error in Lck_Delete(), cache/cache_lck.c line 309:
  Condition((pthread_mutex_destroy(&ilck->mtx)) == 0) not true.

triggered from Lck_Delete(&bytes_tree->nodes_lock) at the bottom of
bytes_tree_fini().

Assuming everything else working correctly, the only scenario I
can see the moment is that we see the node->subreq.done == 1
earlier than Lck_Unlock() returned in vped_task(). In this
case, we could advance to destroying the lock while the other
thread still holds it.

The other use case of the shared lock is in fini_final(), where
we already go through an explicit lock/unlock.

Hopefully fixes #13 for real

The BackendReuse tag no longer exists.

This looks like a trivial oversight in 3370a4c4,
which was meant to fix #10: We need to use the corresponding lock to signal
when a subreq node is done.

Hopefully fixes #13

Avoids "Illegal :path pseudo-header" errors

Ref: 7da66c9b03f82b97e2476d5d0af62e58e0419216

Fixes https://gitlab.com/uplex/varnish/libvdp-pesi/-/issues/10

This brings it down from 120 to 112 bytes for me.

mostly to have it available in tree_free / tree_prune later

We are agnostic to such changes from now on by unsetting the header.

Ref afbe6b648503687b1e9a2571a9e87ab089fc7bee

The minimal version for master should never have been 7.0, but rather 7.1

There is a separate branch for 7.0

Fixes #8

This change does not do anything yet, it just saves the abort flag.

The C compiler checks have been removed as they are already
contained in VARNISH_PREREQ

Avoid permissions issues with the UDS in permutations*.vtc.

We've had reports of these tests failing on some platforms (e.g.
FreeBSD 13), with FetchError reporting EPERM for the backend that
accesses the UDS.

Since it's not a pesi issue, and not related to the properties under
test, we might as well allow fully open access to the UDS.

make check runs varnishtest with -b 2m.
