7b914bfb64 roken: getaddrinfo get_null return errors
get_null() can fail for two reasons.  There can be a memory allocation
issue or the hints->ai_family could be unsupported.  This change
informs the caller of the error state instead of returning success
with an invalid struct addrinfo output parameter.

Fixes #1007

133f517482 rewrite fallthrough to HEIM_FALLTHROUGH to deal with new Apple SDKs
Apple clang version 14.0.0 (clang-1400.0.17.3.1) fails the build
because stds.h defines `fallthrough` as a macro which is then
expanded when base.h evaluates

  # if __has_attribute(fallthrough) && __clang_major__ >= 5

The macOS SDK defines `DISPATCH_FALLTHROUGH` as the macro instead
of `fallthrough`.

This change replaces the use of `fallthrough` in the tree with
`HEIM_FALLTHROUGH` and updates the declaration in configure logic
to define `HEIM_FALLTHROUGH` based upon existing definitions
(if any) of `fallthrough` or `DISPATCH_FALLTHROUGH`.

698bbb5647 roken: Fix time_t overflow checking
INTxx_MIN plus a positive integer of the same type will always be
negative, and so the result will always compare less than a positive
integer. Fix this check so that we produce the correct result when
adding two negative time_t values.

7b3a993236 roken: do not override system network address functions
Roken functions rk_copyhostent(), rk_freeaddrinfo(), rk_freehostent()
rk_getaddrinfo(), rk_getipnodebyaddr(),  rk_getipnodebyname(), and
rk_getnameinfo() should never be built without the "rk_" prefix.  Doing
so overrides the system provided functions of the same name when they
exist.

04527412e3 Follow the Linux kernel's lead on "fallthrough"
The pseudo keyword 'fallthrough' is defined such that case statement
blocks must end with any of these keywords:
 * break;
 * fallthrough;
 * continue;
 * goto <label>;
 * return [expression];
 *
 *  gcc: https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html#Statement-Attributes

The macro is defined either as

  __attribute__((__fallthrough__))

or as

  do {} while (0)  /* fallthrough */

not including the semicolon.

This change implements the Linux kernel style and updates several locations
where "/*fallthrough*/ and /* FALLTHROUGH */ were not previously replaced.

Externally imported code such as libedit, libtommath and sqlite are
restored to their unaltered state.

6426e7550f roken: do not globally define 'timezone' and 'tzname'
ec866e635e
("Windows 10 SDK build fixes") introduced CPP macros

  timezone -> _timezone
  tzname   -> _tzname

but these names are common and the macros rewrite too much.

The name mapping is only required when building strftime.c
with Visual Studio 2017 and later.  Move the definitions
into strftime.c.

ec866e635e Windows 10 SDK build fixes
Build without Win32.mak, and using Universal C Runtime (UCRT)

windows: Check for APPVER, not VCVER for UCRT

When deciding whether UCRT is used (and thus no CRT merge modules), check for
Windows 10 rather than the version of Visual Studio, as we may be building with
an older SDK.

5f63215d0d Always perform == or != operation on cmp function result
Although not required to address bad code generation in
some versions of gcc 9 and 10, a coding style that requires
explicit comparison of the result to zero before use is
both clearer and would have avoided the generation of bad
code.

This change converts all use of cmp function usage from

```
    if (strcmp(a, b) || !strcmp(c, d)) ...
```

to

```
    if (strcmp(a, b) != 0 || strcmp(c, d)) == 0
```

for all C library cmp functions and related:

 - strcmp(), strncmp()
 - strcasecmp(), strncasecmp()
 - stricmp(), strnicmp()
 - memcmp()

071b95e683 roken: fix theoretical leak introduced in 7fbe7be6
split_spec() should free output parameters if it fails. This was not a leak in
practice because its single caller cleaned up anyway, but cleaning up for good

75829cad18 Avoid -Werror=strict-overflow on in rk_dns_srv_order()
In a strict Samba build with -Werror=strict-overflow on Ubuntu 18.04
with gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04)
we see

../../source4/heimdal/lib/roken/resolve.c: In function ‘rk_dns_srv_order’:
../../source4/heimdal/lib/roken/resolve.c:639:7: error: assuming signed overflow does not occur when simplifying conditional to constant [-Werror=strict-overflow]
     if(num_srv == 0)
       ^
cc1: all warnings being treated as errors

This avoids the issue by additionally setting a distinct flag.

f67dd0f903 roken: move Heimdal vis.h extensions to separate header
vis.h is not built on platforms (such as macOS) that already have
that header, which resulted in prototypes for Heimdal-specific
vis.h extensions being absent.

Move those prototypes to a separate header, vis-extras.h, which
must be explicitly included in order to use the Heimdal extensions.
