Make error reporting in socket test programs consistent with other usages by
removing redundant newline, using strerror() and reporting error in
parentheses.
Similar to f6e0d19cc0 but
fixed in the header by making it a proper static inline
function (as some callers treats it as one, so do it
for all now for consistency).

krb5_get_instance() is meant to ensure that the shared library
instance of heimdal loaded by a plugin matches the instance that
loaded the plugin. It works by declaring a static C string whose
memory address will be used as an instance identifier. If the
instance returned from the plugin matches the instance obtain
by the code that loads the plugin, then we can conclude the two
instances are the same.
This doesn't work on Windows 7. When heimdal.dll loads a plugin
that is linked to heimdal.dll, the plugin's heimdal.dll is always
a new instance. However, the requirement for plugin safety is
not that the plugin be the same instance in memory but that they
be the same instance on disk.
This change loads the path name and version string for the module
and generates a hash of those strings as an instance identifier.

libtommath 1.2.0 c403b66082
("hcrypto: import libtommath v1.2.0") needs more from stdint.h
than what Heimdal previously declared. Add more integer type
declarations and integer MIN/MAX macros.
Also, on Windows declare 64-bit integers using __int64 as
"long long" is not supported as 64-bit type across all visual
studio compiler versions.

Add mergesort_r() as a stable sort function that can be used by other
components of Heimdal. Note that there is no standardized prototype for this
function, however it appears that both FreeBSD and glibc would adopt the glibc
convention (where the private data argument appears last). See:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214248
This will help programs that need to URL-escape strings.
Also, this changes `do_hvis()` to not fallback on `do_svis()` for chars in
`extra` -- that `do_hvis()` was doing that seems like an oversight. Christos
Zoulas, of NetBSD, agrees. `do_hvis()` still falls back on `do_svis()` for
characters not in the RFC 1808 / 3986 to-be-escaped set *and* characters not in
the `extra` set -- that much seems to have been the intent.
Now that we're using krb5_net_write() with non-blocking sockets in
ipropd_master, we MUST correctly account for partial writes.
Therefore, roken net_write() called from krb5_net_write() now
returns the number of bytes written when the socket error was
EWOULDBLOCK (or EAGAIN).
Also, fix potential issue on Windows, where errno was used instead
of rk_SOCKET_ERRNO whether or not we used _write() or send().
This is necessary in order to add proper support for CSRs in kx509,
where the KDC can examine all requested KUs/EKUs/SANs, check
authorization, and issue a certificate with all those extensions if
authorized.
This is the convention used by OpenSSL, of encoding all the KU, EKUs,
and SANs being requested as Extensions as they would appear in the
TBSCertificate, then putting those in as a single Attribute in the CSR's
Attributes list with attribute OID {id-pkcs-9, 14}.
- expose all hx509_request_*() functions
- finish support in hx509_request_parse*() for KU, EKU, and SAN CSR
attributes
- finish support in hx509_request_to_pkcs10() for encoding all
requested KU, EKU, and SAN extensions as a CSR extReq (extension request)
- add hx509_request_add_*() support for:
- id-pkinit-san and ms-upn-pkinit-san
- XMPP (Jabber) SAN
- registeredID (useless but trivial)
- add hxtool request-create options for all supported SANs
- add hxtool request-create options for KeyUsage
- add hxtool request-create options for ExtKeyUsage
- add hxtool request-print support for all these things
- fix bugs in existing id-pkinit-san handling
Possible future improvements
- add HX509_TRACE env var and support (it would be nice to be able to
observe why some certificate is rejected, or not matched in a query)
- add testing that CSR creating and printing round-trip for all KUs,
EKUs, and SANs
(probably in tests/kdc/check-pkinit.in)
- add testing that OpenSSL can print a CSR made by hxtool and
vice-versa
- hxtool ca: add KU sanity checking (via hx509_ca_sign() and/or friends)
(don't allow encrypt for signing-only algs)
(don't allow encrypt for RSA at all, or for RSA with small e exponents)
- hxtool request-print: warn about all unknown attributes and
extensions
- hxtool ca: MAYBE add support for adding requested extensions from the
--req=CSR
("Maybe" because CA operators should really verify and authorize all
requested attributes, and should acknowledge that they have, and the
simplest way to do this is to make them add all the corresponding
CLI arguments to the hxtool ca command, but too, that is
error-prone, thus it's not clear yet which approach is best.
Perhaps interactively prompt for yes/no for each attribute.)
- add additional SAN types:
- iPAddress (useless?)
- dNSSrv (useful!)
- directoryName (useless, but trivial)
- uniformResourceIdentifier (useful)
- it would be nice if the ASN.1 compiler could generate print
functions..., and/or even better, to-JSON functions
- it would be nice if we had a known-OID db, including the names of the
types they refer to in certificate extensions, otherName SANs and CSR
attributes, then we could generate a CSR and certificate printer for
all known options even when they are not supported by the rest of
Heimdal
- and we could also get friendly names for OIDs, and we could
resolve their arc names
- longer term, we could also stand to add some ASN.1 information
object system functionality, just enough to make
lib/hx509/asn1_print awesome by being able to automatically decode
all heim_any and OCTET STRING content (better than its current
--inner option)
The fix involves:
- Removing HAVE_STRFTIME from config.h.w32
- Adding strftime.c to the makefile
- Defining timezone and tzname to their windows equivalent
for the compile of this module

strtoull() returns an unsigned long long. However, then the input
string represents a negative number the return value is supposed to
be the unsigned representation of the negative value. Before applying
the negation the value must be cast to (long long).
Change-Id: Icf9e75400ff736819b1f7e0e6fb3c8abd707a23a
strtoll() returns a signed long long not an unsigned long long.
When applying the negation for negatives the value must be cast
from unsigned to signed and then stored in a signed variable
before returning it.

We add roken_get_{shell, username, appdatadir, homedir}() functions. These use
a combination of secure_getenv(), getpwuid_r(), getlogin_r(), or various WIN32
functions to get this information.
Use roken_get_appdatadir() instead of roken_get_homedir() when looking for
dotfiles.
We no longer use it since removing ftp from appl/.
Note that expansion of ~username/ couldn't have been working because
k_getpwnam() was being called with an unsigned short * that was forcibly
cast to char *, but it really was shorts, not chars... Anyone who ever
feels like reviving lib/roken/glob.[ch] will want to fix that...
