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.
(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.
* 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.
(get_directory_index): Ditto.
(process_file): Ditto.
