Rather than exposing a pointer to the mmapped memory and performing IO
directly on this address pass the data through a local buffer and move
the reading and writing of memory into the sharedmem module.
This allows us to support shared memory that is not memory mapped in the
future.

Introduce a struct to pass around the parameters related to the rmtfs
memory, in preparation for supporting multiple memory regions.

The nameserver notifies all registered servers about leaving clients.
Stub the handling of these messages, so they are not confused with the
qmi messages.

In the event that the remote crashes, or for other reasons try to open a
partition that we already have open we should reuse the caller objects,
so that we don't run out of them. This should likely be replaced by a
working mechanism for notifications when the remote is going away.

We don't have a way to notice if the remote crashes and free the memory,
so for now don't mark it as busy and just hand out the same memory the
next time.

GNU coding standards notably specifies:
* install files with the $(DESTDIR) to the target system image
* install files with the $(prefix), not $(PREFIX)
* the default value of $(prefix) should be /usr/local
as per
https://www.gnu.org/prep/standards/html_node/Directory-Variables.html.

The rmtfs address differes from platform to platform, so fetch these
from the device-tree node in /proc instead of hard coding them.

To support creating and parsing requests and indications as well qmic
adds an extra parameter to the tlv alloc and decode functions, so that
this can be used to generate and validate that the qmi packet header is
of the correct type.

The rmtfs tool pushlishes the two QMI services "rmtfs" and "rfsa", and
implements the necessary requests for rmtfs that's needed to boot the
modem subsystem on a Qualcomm based board.
