Using config API to reload DMA buffers is inefficient and hence
a reload API is added

Tty device gets only read/write calls, but console retains
getchar/putchar for convenience.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Previously, transmit was effectively non-blocking - a character either
went into buffer, or -1 was returned. Now it's possible to block if
buffer is full. Timeout is K_FOREVER by default, can be adjusted
with tty_set_tx_timeout() (similar to receive timeout).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
This allows to specify receive timeout, instead of previously
hardcoded K_FOREVER value. K_FOREVER is still the default, and can
be changes after tty initialization using tty_set_rx_timeout() call,
and timeout is stored as a property of tty. (Instead of e.g. being
a param of each receive call. Handling like that is required for
POSIX-like behavior of tty).

All the handling of POSIX file descriptors is now done by fdtable.c.
fs.c still manages its own table of file structures of the underlying
fs lib.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
The table allows to wrap read/write (i.e. POSIX-compatible) semantics
of any I/O object in POSIX-compatible fd (file descriptor) handling.
Intended I/O objects include files, sockets, special devices, etc.
The table table itself consists of (underlying obj*, function table*)
pairs, where function table provides entries for read(), write, and
generalized ioctl(), where generalized ioctl handles all other
operations, up to and including closing of the underlying I/O object.

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.

Macro is used to create contiguous bitmask between the
arguments passed to the macro.
BITS_PER_LONG is computed as the multiplication of predefined
macros `__CHAR_BIT__` and `__SIZEOF_LONG__`.
Both gcc and clang support these predefined macros.
With this change, replace the redundant defintions of

CoAP library is migrated to support over socket based
applications or other higher layer protocols. Most of the
API's and functionality is kept as it is except few changes.
net_pkt/net_buf is removed from CoAP library. Now it expects
a pre-allocated flat buffer and length. If there is not enough
space to append any data, library simply returns an error.
It's user's responsibility to allocate and free memory.
One change in functionality is, earlier coap_pending_clear()
used to clear the memory, but now it's user's responsibility
to free the memory.

If we receive an IPv4 that has broadcast destination address, then
properly handle it.
This means that for
* ICMPv4, if CONFIG_NET_ICMPV4_ACCEPT_BROADCAST is set (this is the
default value) and we receive echo-request then accept the packet.
Drop other ICMPv4 packets.
* TCP, drop the packet
* UDP, accept the packet if the destination address is the broadcast
address 255.255.255.255 or the subnet broadcast address.
Drop the packet if the packets broadcast address is not in our
configured subnet.
In sending side, make sure that we do not route broadcast address
IPv4 packets back to us. Also set Ethernet MAC destination address
properly if destination IPv4 address is broadcast one.
