We *really* need a ccache instance ID tag. In fact, we should probably
never krb5_cc_initialize() a ccache that doesn't have such a tag. But
for now cred_delete() is now safe enough.
If we're racing enough we could complain about symlinks where there were
none. This was very surprising. Make it surprise less.
We should really #ifndef O_NOFOLLOW that code chunk too, for the obvious
reason that we don't need to worry about symlinks if we have and use
O_NOFOLLOW.
Also, since all uses of fcc_open() use O_NOFOLLOW we should move that
into fcc_open(). Ditto O_BINARY and O_CLOEXEC.
Patchset 58ff480763 calls write() and read()
on rk_socket_t objects which on Windows are SOCKETs not C RTL file
descriptors. This patchset uses krb5_net_write() and krb5_net_read()
in place of the direct write() and read() operations.

Windows plugins must be loaded from the same directory as the
heimdal.dll in order to ensure that "DLL Hell" is not revisited.
Since plugins cannot be grouped in a directory by "module" name
the plugins must have a name of the form:
plugin_<module>_<name>.dll
Construct the "plugin_<module>_" prefix string dynamically and
test for both the prefix and the ".dll" extension when building
the list of plugins to load.

rename callback() to cc_plugin_register_to_context() and document
its purpose.
The parameter that is the cc_ops structure is 'plugctx' not 'plug'.
This is critical because 'plug' is the common_plugin_model structure
and casting the wrong object leads to random behavior including
crashes.
The test to exit without action was reversed.
With these changes ccache plugins can be registered on each
krb5_init_context() operation.

Windows treats '\\' and '/' equivalently but we cannot control
the form that will be used by end users. Introduce ISPATHSEP()
macro which tests only for '/' on UNIX and both on Windows.
Introduce ISTILDE() macro to test for '~'. When testing for
'/' with strchr() or strrchr() add conditional checks for '\\' on
Windows.

st_dev and st_ino are not set in a consistent fashion by stat()
and fstat() so disable the symlink test.
disable the open group/other readable test because st_mode
cannot be used to perform such a test on Windows.

Do not look for plugin DLLs in either

Rely on roken to determine which random function should be
used.
Rename parameter "rand" to "randbytes" to avoid collision with
functions named "rand()".

Normally one would dlopen() a shared object's basename, not its absolute
path. However, lib/krb5/plugin.c, in an effort to be zero-conf-ish,
wants to readdir() to find plugins to load, and in the process it ends
up defeating the RTLD's search-the-caller's-rpath.
This commit partially addresses this by allowing the use of $ORIGIN in
plugin_dir values and using them for the default (except on OS X).
This allows multiple Heimdal versions installed on the same host, but
with different plugin ABIs, to co-exist. A step forward for doing make
check on hosts where Heimdal is installed.
For now we hardcode $ORIGIN/../lib/plugin/krb5 (linux, Solaris, *BSD),
or $ORIGIN (Windows; for assemblies objects need to be in the same
directory) and we eval $ORIGIN by using dladdr() (Linux, Solaris) or
GetModuleHandleEx() (Win32, via a dladdr() wrapper in libroken) to find
the path to libkrb5 whose dirname to use as $ORIGIN. For Windows,
because we need the plugins to be in the same directory as libkrb5, we
require a prefix on plugin DLLs ("plugin_krb5_") to distinguish them
from other objects.
We should add a special token to mean "look in $ORIGIN, sure, but
dlopen() the plugin basenames only (so the RTLD can search the rpath)".
rk_mkdir() should not be redefined to mkdir() nor should mkdir()
be redefined to rk_mkdir() when compiling lib/roken/mkdir.c

Although rk_mkdir can be provided on all platforms there is no
reason to require that it be used by unconditionally mapping
mkdir -> rk_mkdir
