Throughout, change 'cygwin_shared.mount' to 'mount_table'.

Browse Source 
* child_info.h (child_info): Move shared_h, console_h to cygheap.  Add mount_h.
* cygheap.h (init_cygheap): Add shared_h, console_h.
* cygheap.cc (init_cheap): Initialize heap at a fixed location after the shared
memory regions.  Initialize cygheap->user name here.
* dcrt0.cc (dll_crt0_1): Call getpagesize () to initialize constants.  Remove
cygheap_init since it is done in shared_init now.
(_dll_crt0): Initialize mount_h, remove shared_h and console_h initialization.
* fhandler_console.cc (console_shared_h): Eliminate.
(get_tty_stuff): Use cygheap->console_h rather than console_shared_h.
* heap.cc (heap_init): Use page size constant calculated earlier in
initialization.
* shared.cc: Eliminate cygwin_shared_h.  Add cygwin_mount_h.
(mount_table_init): New function for initializing a user mount table.
(open_shared_file_map): Use constant for shared memory region.  Initialize
cygheap and mount table here.
(open_shared): Improve debugging output.
(shared_info::initialize): Eliminate call to mount.init.
(shared_terminate): Use cygheap->shared_h.  Close cygwin_mount_h.
(open_shared_file_map): Eliminate.
* shared_info.h (mount_info): Add a version field.
(shared_align_past): New macro for calculating location for shared memory
regions.
* sigproc.cc (init_child_info): Eliminate shared_h, console_h.
* spawn.cc (spawn_guts): Pass on cygwin_mount_h iff not a different user.
* syscalls.cc (system_info): New global holding system memory defaults.
(getpagesize): Use system_info.
* uinfo.cc (internal_getlogin): Only fill in user name if nonexistent.
* winsup.h: Declare system_info.
* passwd.cc (read_etc_passwd): Use cygheap->user.name () rather than retrieving
the name again.
