Error messages of regtool can't be read, which are encoded in,
for instance, SHIFT_JIS in Japanese Windows. Fix by using
wide chars instead of multibyte.
Recent versions of gcc are optimizing away the TLS buffer allocated in
main, so we need to tell gcc that it's really used. RtlSecureZeroMemory
accomplishes this while also inlining the memset.

Ensure that ldd always stops when the exception is flagged as
non-continuable.
Also arrange for ldd to exit with a non-zero exit code if something went
wrong which prevented us from listing all dynamic dependencies.

The form data sent to the server should be application/x-www-form-urlencoded
This replaces spaces with '+' before being RFC 1738 encoded, so a literal
'+' must be %-encoded also.

The new functionality to set the thread name for debugging purposes
creates exception debugging events. These are printed out when running
strace. Since these exceptions have nothing to do with real exceptions
but are, like breakpoint execptions, expected and non-fatal, don't print
exception info for them.

On Windows 8.1 and later, the NetUserChangePassword call apparently
doesn't accept the usual "\\server" string anymore, but requires to
use the "domain" instead, otherwise it emits en error code 1265,
ERROR_DOWNGRADE_DETECTED. Since this is accepted by pre-8.1 as well,
use the domain indiscriminately when calling NetUserChangePassword
from passwd(1).
While at it, do some minor cleanup in passwd.c.

The default UI language returned by GetUserDefaultUILanguage does not
necessarily reflect what the user really wants. E. g., the system could
be en_US, but the desired language is en_CA, without having a CA langpack
installed.
Changing the settings under "Languages" and changing the keyboard layout
is only affecting the so-called "Input language", while what's returned
by GetUserDefaultUILanguage is the "Display language". Changing the
latter requires installing MUI langpacks.
Thus, we introduce a way to fetch the "Input language" using the -i or
--input option.
Also clean up documentation of locale(1).

set_entry_point_break() uses GetModuleInformation to fetch the
address of the exe's entry point. However, just as with
lpStartAddress from the CREATE_PROCESS_DEBUG_EVENT event, the
returned address is only computed from the PE file header. It's
not actually the entry point in memory, if the executable is
relocated (ASLR). See
https://msdn.microsoft.com/en-us/library/windows/desktop/ms684229(v=vs.85).aspx
Convert this to using the info from CREATE_PROCESS_DEBUG_EVENT
combined with the offset from the PE file header's AddressOfEntryPoint
to deal with relocation.

So far ldd terminates the inferior process as soon as some thread

before the main thread of the application is started. As a result
the dll list is cut short since ldd terminates prematurely.

Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.
Other than that, cygwin_props were meant to be used for some other global
settings which never took place. There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.
This patch removes the cygwin_props entirely, including the related
settings in cygcheck.
cygwin:
* cygprops.h: Remove file.
* globals.cc (cygwin_props): Remove.

installation key.

values.

(handle_unique_object_name): Remove function.

Fix various 32/64-bit portability issues in ssp, the single-step profiler, and
also build it for 64-bit.
This didn't turn out to actually be very useful for what I wanted to use it for,
so it's only been lightly tested.
It appears that on x86_64, single-step exceptions occur for much more of the
code in system DLLs, unlike x86, so ssp may take much, much longer to profile
some programs. There is existing code to use breakpoints to mitigate this, but
that is currently disabled.

On Cygwin 32 running under WOW64:
When case-correcting the path fetched with -S, the underlying
Windows function fetching the normalized path returns the real
path C:\Windows\SysWOW64 instead of the path redirection
enabled C:\Windows\System32 path. This breaks using the result
of `cygpath -S' to fetch the POSIX path of the network related
files under SYSTEMROOT\drivers\etc. This path is in fact under
the *real* C:\Windows\System32 and only mapped into the 32 bit
C:\Windows\System32 (aka C:\Windows\SysWOW64) via path redirection.
Sounds messy?
This patch checks if we're running under WOW64. If so, it
changes the path returned by GetSystemDirectoryW from "system32"
to "Sysnative". This in turn is changed to "System32" by
NtQueryInformationFile, so we're back to what we need.
