Corinna Vinschen 5489240c1b Cygwin: fix declaration of __small_{v}sprintf
Both functions are declared as extern "C" functions in
sys/smallprint.h, but as C++ funcs in winsup.h and in the
source itself.

Add extern "C to definitions, remove declarations in winsup.h
and include sys/smallprint.h instead.

Takashi Yano 83b2d576c8 Cygwin: pty: Limit API hook to the program linked with the APIs.
- API hook used for pseudo console support causes slow down.
  This patch limits API hook to only program which is linked
  with the corresponding APIs. Normal cygwin program is not
  linked with such APIs (such as WriteFile, etc...) directly,
  therefore, no slow down occurs. However, console access by
  cygwin.dll itself cannot switch the r/w pipe to pseudo console
  side. Therefore, the code to switch it forcely to pseudo
  console side is added to smallprint.cc and strace.cc.

Takashi Yano ffbb9b4971 Cygwin: pty: Move function hook_api() into hookapi.cc.
- PTY uses Win32 API hook for pseudo console suppot. The function
  hook_api() is used for this purpose and defined in fhandler_tty.cc
  previously. This patch moves it into hookapi.cc.

Michael Haubenwallner ece7282f32 forkables: On fork failure, retry with hardlinks.
To support in-cygwin package managers, the fork() implementation must
not rely on .exe and .dll files to stay in their original location, as
the package manager's job is to replace these files.  Instead, when the
first fork try fails, and we have NTFS, we use hardlinks to the original
binaries in /var/run/cygfork/ to create the child process during the
second fork try, along the main.exe.local file to enable the "DotLocal
Dll Redirection" feature for the dlls.

The (probably few) users that need an update-safe fork manually have to
create the /var/run/cygfork/ directory for now, using:
mkdir --mode=a=rwxt /var/run/cygfork

	* child_info.h: Bump CURR_CHILD_INFO_MAGIC.
	(enum child_status): Add _CI_SILENTFAIL flag.
	(struct child_info): Add silentfail setter and getter.
	* winsup.h (child_copy): Add bool silentfail parameter.
	* cygheap.cc: Pass silentfail parameter to child_copy.

	(struct dll_list): Declare private method find_by_forkedntname.
	* dll_init.cc (struct dll_list): Implement find_by_forkedntname.
	(dll_list::alloc): Use find_by_forkedntname when in load after fork.
	(dll_list::load_after_fork_impl): Load dlls using dll::forkedntname.
	* fork.cc (frok::parent): Set silentfail child info flag.  Pass
	silentfail parameter to child_copy.  Use forkedntname of
	dlls.main_executable.
	(fork): When first dofork run failed and did not use forkables,
	run dofork again with_forkables set to true.
	(child_copy): Use debug_printf if silentfail is true,
	system_printf otherwise.

	overrides back into the DLL's global per_process data.
