Now Open MPI requires a C99 compiler. Checking availability of
the following types is no more needed.
- `long long` (`signed` and `unsigned`)
- `long double`
- `float _Complex`
- `double _Complex`
- `long double _Complex`
Furthermore, the `#if HAVE_[TYPE]` style checking is not correct.
Availability of C types is checked by `AC_CHECK_TYPES` in `configure.ac`.
`AC_CHECK_TYPES` defines macro `HAVE_[TYPE]` as `1` in `opal_config.h`
if the `[TYPE]` is available. But it does not define `HAVE_[TYPE]`
(instead of defining as `0`) if it is not available. So even if we
need `HAVE_[TYPE]` checking, it should be `#if defined(HAVE_[TYPE])`.
I didn't remove `AC_CHECK_TYPES` for these types in `configure.ac`
since someone may use `HAVE_[TYPE]` macros somewhere.

Simplify selection of the address to publish for a given BTL TCP
module in the module exchange code. Rather than looping through
all IP addresses associated with a node, looking for one that
matches the kindex of a module, loop over the modules and
use the address stored in the module structure. This also
happens to be the address that the source will use to bind()
in a connect() call, so this should eliminate any confusion
(read: bugs) when an interface has multiple IPs associated with
it.

Today, a btl tcp module is associated with exactly one IP
address (IPv4 or IPv6). There's no need to reserve space
for both an IPv4 and IPv6 address in the module structure,
since the module will only be associated with one or the
other.

Work around a race condition in the TCP BTL's proc setup code.
The Cisco MTT results have been failing on TCP tests due to a
"dropped connection" message some percentage of the time.
Some digging shows that the issue happens in a combination of
multiple NICs and multiple threads. The race is detailed in
https://github.com/open-mpi/ompi/issues/3035#issuecomment-429500032.
This patch doesn't fix the race, but avoids it by forcing
the MPI layer to complete all calls to add_procs across the
entire job before any process leaves MPI_INIT. It also
reduces the scalability of the TCP BTL by increasing start-up
time, but better than hanging.
The long term fix is to do all endpoint setup in the first
call to add_procs for a given remote proc, removing the
race. THis patch is a work around until that patch can
be developed.

This commit fixes a deadlock that can occur when using a TL that
supports the connect to endpoint model. The deadlock was occurring
while processing an incoming connection requests. This was done from
an active-message callback. For some unknown reason (at this time)
this callback was sometimes hanging. To avoid the issue the connection
active-message is saved for later processing.
At the same time I cleaned up the connection code to eliminate
duplicate messages when possible.
This commit also fixes some bugs in the active-message send path:
- Correctly set all fragment fields in prepare_src.
- Fix bug when using buffered-send. We were not reading the return
code correctly (which is in bytes). This resulted in a message
getting sent multiple times.
- Don't try to progress sends from the btl_send function when in an
active-message callback. It could lead to deep recursion and an
eventual crash if we get a trace like
send->progress->am_complete->ob1_callback->send->am_complete...

This commit updates the uct btl to change the transports parameter
into a priority list. The dc_mlx5, rc_mlx5, and ud transports to the
priority list. This will give better out of the box performance for
multi-threaded codes beacuse the *_mlx5 transports can avoid the mlx5
lock inside libmlx5_rdmav2.
This commit also fixes a number of leaks and a possible deadlock when
using RDMA.

The Open MPI code base assumed that asprintf always behaved like
the FreeBSD variant, where ptr is set to NULL on error. However,
the C standard (and Linux) only guarantee that the return code will
be -1 on error and leave ptr undefined. Rather than fix all the
usage in the code, we use opal_asprintf() wrapper instead, which
guarantees the BSD-like behavior of ptr always being set to NULL.
In addition to being correct, this will fix many, many warnings
in the Open MPI code base.

This commit works around an Oracle C compiler bug in 5.15 (not sure
when it was introduced). The bug is triggered when we chain
assignments of atomic variables. Ex:
_Atomic intptr x, y;
intptr_t z = 0;
x = y = z;
Will produce a compiler error of the form:
operand cannot have void type: op "="
assignment type mismatch:
long "=" void
To work around the issue we are removing the chain assignment and
setting the head and tail on different lines.

Remove the pack/unpack pragma around net/if.h on MacOS, which
was added to fix a bug in MacOS X 10.4.x on 64-bit platforms.
The bug was fixed in Mac OS X 10.5.0 and, sometime in the last
11 years, compilers started emitting warnings about the fact
that the Apple header stomped over the pragma pack settings
from the workaround. We already don't support versions of MacOS
earlier than 10.5, so there's no point in keeping the workaround.

Per
https://github.com/open-mpi/ompi/issues/3035#issuecomment-426085673,
it looks like the IP address for a given interface is being stashed in
two places: on the endpoint and on the module.
1. On the endpoint, it is storing the moral equivalent of a
(struct sockaddr_in.sin_addr).
2. On the module, it is storing a full (struct sockaddr_storage).
The call to opal_net_get_hostname() expects a full (struct sockaddr*)
-- not just the stripped-down (struct sockaddr_in.sin_addr). Hence,
when the original code was passing in the endpoint's (struct
sockaddr_in.sin_addr) and opal_net_get_hostname() was treating it
like a (struct sockaddr), hilarity ensued (i.e., we got the wrong
output).
This commit eliminates the call to opal_net_get_hostname() and just
calls inet_ntop() directly to convert the (struct
sockaddr_in.sin_addr) to a string.
NOTE: Per the github comment cited above, there can be a disparity
between the IP address cached on the endpoint vs. the IP address
cached on the module. This only happens with interfaces that have
more than one IP address. This commit does not fix that issue.
