* Makefile.in (DLL_OFILES): Add pseudo-reloc.o.

Browse Source 
* dcrt0.cc (child_info_fork::handle_fork): Call _pei386_runtime_relocator here.
(dll_crt0_1): Ditto for non-fork case.
* dll_init.cc (dll::init): Complain more in comment.  Clean up slightly.
(dll_dllcrt0_1): Call _pei386_runtime_relocator when we know we have a
filled-in per_process structure.
* globals.cc (__cygwin_user_data): Accommodate new fields for
_pei386_runtime_relocator.
* pseudo-reloc.cc: New file adapted from old lib/pseudo-reloc.c.  Include
winsup.h directly.  Collapse #ifdef __CYGWIN__ into one block.  Perform minor
whitespace code reformatting.
(__report_error): Use small_printf to output error.
(_pei386_runtime_relocator): Conditionalize for cygwin to take per_process
pointer parameter.
* winsup.h (_pei386_runtime_relocator): Declare.
* include/cygwin/version.h
(CYGWIN_VERSION_PER_PROCESS_API_VERSION_COMBINED): New macro.
(CYGWIN_VERSION_USER_API_VERSION_COMBINED): Use above macro.
(CYGWIN_VERSION_USE_PSEUDO_RELOC_IN_DLL): New macro.
(CYGWIN_VERSION_API_MINOR): Bump to 227.
* include/sys/cygwin.h: Remove obsolete comment.
(per_process::unused2): Shorten.
(per_process::pseudo_reloc_start): New field.
(per_process::pseudo_reloc_end): Ditto.
(per_process::image_base): Ditto.
* lib/_cygwin_crt0_common.cc: Declare pseudo runtime externs needed for
per_process structure.
(_cygwin_crt0_common): Fill in pseudo_reloc runtime constants.
* lib/pseudo-reloc-dummy.c: New file.  Dummy function to satisify ld.
* lib/pseudo-reloc.c: Delete.
