* cygheap.h (mini_cygheap): New struct.

Browse Source 
(init_cygheap): Inherit locale field via mini_cygheap.
* cygheap.cc (cygheap_at_start): Define new variable.
(cygheap): Initialize as cygheap_at_start so that locale information is always
available.
(cygheap_init): Initialize cygheap iff it is set to cygheap_at_start.
* shared_info.h (memory_init): Accommodate argument change.
* memory.cc (memory_init): Accept an argument indicating whether cygheap should
be initialized or not.
* dcrt0.cc (child_info_fork::handle_fork): Pass false to memory_init().
(child_info_spawn::handle_spawn): Ditto.
(dll_crt0_0): Pass true to memory_init when not forking or execing.
* cygheap.h (cygheap_types::HEAP_2_DLL): New enum.
* dll_init.h (dll): Remove unused namelen field.
(dll_list::load_after_fork): Accommodate change in arguments.
* dll_init.cc (dll_list::alloc): Allocate dll information in the cygwin heap.
(dll_list::detach): Free dll information from the cygwin heap.
(dll_list::load_after_fork): Use dll information in the cygwin heap directly
rather than querying parent.
* fork.cc (frok::first_dll): Delete.
(frok::child): Don't report on first_dll.  Don't pass it to load_on_fork.
(frok::parent): Don't set first_dll.
(fork): Ditto.
