If a client application is built against 19.08, it can dump the "manifest" of API signatures.
Either the all APIs (--dump) or the APIs it is interested in (--dumpfiltered).
When the developers of said client application wants to verify that it works with VPP 20.01.
It can connect to VPP and --validate the old mainfest file, and will be told a list of
messages (both request and reply) that has changed.

In the previous implementation of socket transport for PAPI,
socket methods .send and .recv_into were used.
But they are not guaranteed to send/receive all the data
for the full message. The receive part contained a loop,
but it handled only the main message, not the header.
This patch replaces .send with .sendall
and uses newly defined _read_fixed method.
Also, removed Paul from maintainers,
as he is not active much, lately.

Previously, self.transport.q got the messages
(at least for socket transport), stored in the encoded (packed) form.
In order to avoid accessing internals for async reads,
a new method is introduced, to perform
blocking reads of decoded (unpacked) messages.
The method is also used in _call_vpp(),
so sync and async reads are kept compatible.

In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files.
In two formats, "custom-dump" and "dump". "dump" gives a human friendly list,
and "custom-dump" is meant to give a list of commands that can be fed to VAT.
This patch only deals with "dump".
Prior to this fix, auto-generation was only done for the basic types.
This fix adds support for any type, including lists, and supports pretty-printing
of enums, strings, IP addresses, MAC addresses and so on.
Usage: api trace dump <api-trace-file>
For example

Callback receives "reply" messages containing context,
but previously there was no easy way
to get the automatically generated context value
of the originally sent "command" message.
With this, the caller can store the contexts,
so the callback knows which command got replied to.

Enforce that variable length fields are the last element of API messages.
Add a 'fixed' version of string type, since dealing with
multiple variable length strings turned out too painful
for the C language bindings.
The string type is now:
{
string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64]
string name[]; // Variable length string with embedded len field (vl_api_string_t)
};
The latter notation could be made available to other types as well.
e.g.
{
vl_api_address_t addresses[];
}
instead of
{
u32 n_addr;
vl_api_address_t addresses[n_addr];
};

Now that we have support for f64:
- create explicit types for timestamp(datetime)/timedelta
- update log_details to use timestamp and remove redundant string representation.
If you need the string representation, in python do str(timestamp).
If you prefer the raw f64 value, the client can pass in the
_no_type_conversion option.

As the injected logger is already expected
to be used everywhere, this is a fix.
The few lines in vpp_serializer.py are not fixed,
but they are not encountered in CSIT testing.
Functions call_logger and return_logger
have single call site each (and confusing names, as they do not log),
so saved few lines by inlining them.

clib_net_to_host_f64, clib_host_to_net_f64 are now implemented as '=',
https://gerrit.fd.io/r/#/c/20406/ set papi to match.
- all f64 api references are now wrapped with
clib_net_to_host_f64 or clib_host_to_net_f64.
IEEE f64 endianess is not defined. If clib_net_to_host_f64 and
clib_host_to_net_f64 are later defined in VPP as big-endian, it is
a single character change in the papi vpp_serializer.
Note: This breaks the api in a manner that would not be detected by
the flag day initiative. The scope is small. This only impacts map.api,
which applied the u64 transformation, while the gbp api uses '='.
The implementation of "=" raises issues for the papi socket implementation
if used between systems of differing endianess. See Vratko's comments.
- Added get_f64_endian_value() to api to allow client to verify endianess of f64's.
