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.

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
is started. Apparently threads are started from even ntdll.dll
before the main thread of the application is started. As a result
the dll list is cut short since ldd terminates prematurely.

Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause.
Everything else stays under GPLv3+.
New Linking Exception exempts resulting executables from LGPLv3 section 4.
Add CONTRIBUTORS file to keep track of licensing.
Remove 'Copyright Red Hat Inc' comments.

option handling to use the same style throughout all Cygwin utils.
Throughout use program_invocation_short_name to refer to current
process name in Cygwin executables.
* utils.sgml: Align documentation to above change. Add missing
sections for getconf, ldd, and setmetamode.
* strace.cc (proc_child): Avoid compiler warning.

invalid path, now that this is done in cygwin_conv_path.
|

(head): Move earlier.
(saw_file): Ditto.
(print_dlls): Reset head here. Record seen dll names so they will not
potentially be printed later.
(process_file): Remove clearing of head here.

* strace.cc (proc_child): Ditto.
* ldd.cc: Remove now useless undef wcscasecmp.

* passwd.c: Use mbstowcs instead of MultiByteToWideChar throughout.
(main): Call setlocale. Fix a bug in fetching the logon server from
the environment.

(set_entry_point_break): Rename from get_entry_point.
(print_dlls): Rename from print_dlls_and_kill_inferior. Avoid printing
specific dll name if we're looking at a dll.
(report): Always dump dlls on process exit. Don't allow thread creation.
Accommodate get_entry_point rename.
(start_process): Start process with DEBUG_ONLY_THIS_PROCESS.
(longopts): Eliminate "dll" option.
(main): Ditto.
* ldd.cc: Use wide character Win32 paths throughout.
(load_dll): Fix size expression (add fn) in realloc.

(get_module_filename): Generalized wrapper function which avoid path length
restrictions.
(load_dll): Handle special-case of inspecting a DLL.
(start_process): Accept an output parameter "isdll". Detect when file to start
is a DLL and start a wrapper instead.
(print_dlls_and_kill_inferior): When dealing with a DLL, avoid printing
everything before the DLL itself first appears. (This is not strictly correct
and should be fixed eventually)
(report): Deal with DLLs. Don't set a breakpoint for DLLs, just let captive
ldd process terminate normally. Pass dll info to print_dlls_and_kill_inferior.
(main): Handle special-case "--dll" option by loading the DLL and exiting.

(start_process): Change to expect windows filename as input.
(tocyg): New function - convert cygwin fn to windows fn.
(print_dlls_and_kill_inferior): Accept extra argument denoting whether to open
input and look for nonexistent DLLs. Use tocyg to convert filename and pass it
to start_process.
(report): Flag when an DLL-not-found exception occurs and pass this information
to print_dlls_and_kill_inferior.
(filelist): New structure.
(saw_file): New function.
(dump_import_directory): Ditto.
(map_file): Ditto.
(skip_dos_stub): Ditto.
