31e583e9f8 lib/nfs: initial support for libnfs API 2 
Commit
5e8f7ce273
introduced the libnfs API version 2 which may eventually become libnfs
version 6.

This version detection depends on my pull request

98f53b6d3d lib/nfs/Connection: add DisposablePointer parameter to CancelAndClose() 
Just in case somebody needs to free a buffer after the NFS
cancellation has completed.

5cffd4f673 lib/nfs/Connection: remove EnableCloseOnExec() call 
SOCK_CLOEXEC has been added to libnfs version 2, and since we require
at least version 4, we can safely remove this call.

64c291ba78 lib/nfs/Connection: suppress bogus clang warning 
We do need to capture "this" because we use "this->active_leases", but
clang 18 is too dumb to understand this.

f0ac0c19b7 lib/nfs/Connection: remove obsolete debug field "in_destroy" 
This is obsolete because PrepareDestroyContext() no longer calls
nfs_destroy_context().

ba1b8533a5 lib/nfs/Connection: fix assertion failure on mount timeout 
When nfs_destroy_context() is called while nfs_mount_async() is in
progress, libnfs invokes MountCallback(-EINTR) (but only if a NFS RPC
call is in progress; if the TCP connect is in progress, that callback
is not invoked).

If the mount operation had timed out, OnMountTimeout() set
mount_state=FINISHED, which triggered an assertion failure in
MountCallback(); this commit adds a check on whether the mount has
timed out and ignores the MountCallback.

227ab998bc lib/nfs/Connection: pass status and data to the NfsClientError ctor 
This way, we avoid calling the FormatNfsClientError() which crashes
when nfs_get_error() returns nullptr; that can happen on RPC errors:
then, libnfs's check_nfs4_error() doesn't call nfs_set_error().

9384bff6f9 lib/nfs/Manager: add method MakeConnection() 
This uses the libnfs function nfs_parse_url_dir() which means MPD
gains support for the libnfs arguments like "version".

615f6f50ce lib/yajl: drop "yajl/" prefix from #include paths 
According to the yajl API documentation, #include lines should have
the "yajl/" path prefix, but the actual pkg-config file contains:

 includedir=${dollar}{prefix}/include/yajl

.. which already contains this directory name, and thus the "yajl/"
prefix cannot work.  Unfortunately, the yajl project hasn't been
maintained for nearly 10 years, and there's little chance this bug
will ever be fixed.

00cf036d58 lib/avahi/Client: relax assertion after COLLISION/REGISTERING 
Turns out that `AVAHI_CLIENT_S_COLLISION` can occur after
`AVAHI_CLIENT_S_RUNNING`, and `connected==true`.  Relaxing this fixes
a bogus assertion failure.

of Publisher-owned in a std::forward_list.
