move modules symbols_in_program, pecoff_symbols_in_program and macho_symbols_in_program to new folders linux, win and macosx

use is_using_desc_relative_to_array in module graph_copy_with_names, adjust descriptor addresses relative to the address of __ARRAY__ if necessary (because of position independent code)

use function is_using_desc_relative_to_array in module graph_to_string_and_descriptors, add the address of __ARRAY__ to descriptors if it yields 1 (to fix the descriptors for position independent code)

use abc instructions get_desc_arity_offset and load_module_name in module graph_to_string_and_descriptors_macho

use preprocessor symbol USE_DESC_RELATIVE_TO_ARRAY instead of MACH_O64 for array element descriptors also in copy_string_to_graph.c

use preprocessor symbol USE_DESC_RELATIVE_TO_ARRAY instead of MACH_O64 for array element descriptors in copy_graph_to_string.c

use abc instruction load_module_name in modules graph_copy_with_names and graph_to_string_and_descriptors

in module pecoff_symbols_in_program read base_of_date for 64 bit windows (now ported to 64 bit windows)

Fix "Error reading symbol table" when auxiliary entries are in the symbol table and the symbol table is located at the end of the executable. Auxiliary entries count as symbol entries.

Fix "Error reading symbol table" when auxiliary entries are in the symbol table and the symbol table is located at the end of the executable. Auxiliary entries count as symbol entries.

add modifications in 2 commits from Arjan Oortgiese: The function id generated by the C backed was used. For example the Lambda function name is \;19;31;5.6, the 6 is used instead of the 5. We remove thus first the function id from the C backed before processing the name. and Remove C backend function number.

use n>>1 instead of n/2

add member types with strictness annotations to {!} and {#} instances (the compiler currently adds these annotations)
