btr: splice-out fix.
When splicing out a node we set the ->parent pointer of all child
nodes to the parent of the given node, and move each child to the
->children list of the parent.
Except when there is no parent. If the given node was a root node
(or an internal node whose parent vanished), we leave the ->children
list untouched. In this case the assertion a few lines later triggers
and aborts the program. Fix this by removing the nodes from the list.
Such nodes have become root nodes themselves, so they should not be
on any list of children.

The size of the buffer tree pool of the amp filter is 64K, which
is smaller than BTRN_MAX_PENDING of buffer_tree.c (96K). The latter

tree node is available and there is less than BTRN_MAX_PENDING bytes

server/gcrypt: Fix sending the empty status items.
When para_server enters the "stopped" state, it needs to inform all
clients which are executing the stat command that no audio file is
currently available.
To this aim the stat command handler calls empty_status_items(), which
creates a buffer containing empty values for most status items. This
function tries to be smart by computing the buffer only once. It
saves a reference in a static variable so that on subsequent calls
it can simply return the same buffer.
This works fine when para_server is compiled against the openssl
crypto library. However, it fails when libgcrypt is used because with
libgcrypt the send buffer is encrypted in-place. Hence on subsequent
calls the already encrypted buffer will be encrypted again, resulting
in garbage being sent to the client.
This patch avoids this bug by using a fresh buffer each time the
empty status items are sent.

This is because O_NONBLOCK is a file status flag rather than a file
descriptor flag, i.e. nonblocking mode is a property of the file
description rather than the file descriptor.
In the above command both stdin of the para_client process and
stdout of the grep process refer to the same file description (the
terminal). para_client sets stdin to nonblocking mode, hence stdout
of the grep process is also in nonblocking mode.
We avoid this problem by changing client.c to only set stdin to
nonblocking mode if we actually need to read from stdin, i.e. only
for the addblob commands. This is achieved by registering the stdin
task (which sets the O_NONBLOCK flag) only if the client status
is CL_SENDING.
For addblob commands the client status changes from CL_EXECUTING to
CL_SENDING, so we can not simply terminate the supervisor task any more
after the stdout task has been registered. Instead we must keep this
task alive and (a) remember that stdout has already been started, and
(b) start the stdin task in case the client status becomes CL_SENDING.
Unfortunately, there is no simple way to store this bit of information
as we don't have a dedicated supervisor structure yet. Therefore this
patch introduces this structure as a task struct plus a single boolean.

space characters in chunks rather than one at a time. It introduced
space[], an array of whitespace characters, which is written entirely
if there are more spaces to print than the size of the array. However,
in the calculation of how much was printed so far, we missed the fact
that sizeof(space) includes the terminating NULL byte, so this number
is in fact the number of space characters *plus one*.
Consequently, we printed too few space characters. This resulted in
parts of the previous string still being visible in the top window
of para_gui.
