Regression: Invalid type used when allocating string, f_string_t should instead be f_char_t.
I noticed odd differences between the 0.6.x and the 0.7.x in terms of memory usage.
I discovered this to be due to a bug where the f_string_t is being used when the type should be instead f_char_t.
This is likely a bug introduced in some past refactor.

Bugfix: The socket id is not the same descriptor for reading.
When binding and listening on some socket id, the accept call on that socket creates a new descriptor.
That descriptor is not the same as the original socket id.
Add a new id_data to the socket structure to represent the data transfer file descriptor that is created via the accept() call.
Add a new f_file_close_id() to close the file by the id in case the f_file_t is not available or in use.
This adds f_time_spec_millisecond() and f_time_spec_nanosecond() for safely handling overflow and underflow when using standard FLL f_number_unsigned_t numbers.
Unit tests are added.
A comment in the controller prrogram is added to designate that the controller-specific functions should be updated to call these functions.

There are still the append() and append_all() function to change but I am going to leave that for another time.
This finishes the recent set of Progress commits addressing the memory array related code.
I have observed a notable reduction in binary size but the primary goal here is reduction of duplicate code and simplification of code.
I should eventually be able to re-introduce macros to map these helper functions back to the base array type to reduce binary size by a significant amount.
This should only be done once the API has stabilized more.

Progress: Continue memory array related changes.
I noticed that I could also implement f_memory_array_append() and f_memory_array_append_all() methods if I used memcpy() and a multiplication over the type size.
This:
const f_status_t status = f_memory_array_increase_by(source.used, sizeof(f_socket_t), (void **) &destination->array, &destination->used, &destination->size);
if (F_status_is_error(status)) return status;
for (f_number_unsigned_t i = 0; i < source.used; ++i) {
destination->array[destination->used++] = source.array[i];
} // for
return F_none;
Could instead become:
const f_status_t status = f_memory_array_increase_by(source.used, sizeof(f_socket_t), (void **) &destination->array, &destination->used, &destination->size);
if (F_status_is_error(status)) return status;
This could then be logic could then be moved into something like f_memory_array_append_all(), further simplifying the code into:
return f_memory_array_append(source.array, source.used, sizeof(f_socket_t), (void **) &destination->array, &destination->used, &destination->size);

The pattern for handling the standard array structure is now well established.
Provide a memory array functionality for handling the most basic form.

It would be interesting if this reduces the size of the resulting binary but with inline optimizations it may be possible that this actually increases the size of the resulting binary.

Update: Add FSS Simple Packet related functionality and remove delimit and comment types.
The FSS Simple Packet functionality is added, to provide for processing of the FSS Simple Packet.
The f_fss_simple_packet_ranges_t represents a set of ranges for designating where/how the packet is defined within some string.
The delimit and comment types are just helper type definitions for existing number types.
Simplify the design by getting rid of those, replacing them with the type that they effectively represent.
A lot of code is updated to reflect this change.
This is an encrypted variation of the FSS-000F "Simple Packet" specification.
The third control bit (from the left) represents that the Simple Packet is encrypted.
The requirements for the format of the actual contents of Payload Block is further relaxed due encrypted data needing to be private (for what should be obvious reasons).
Add "Properties: " and related styling to the documentation comments for type definition structures.
Fix capitalization and other formatting issues that I noticed.

Update: Conversion should return F_number_positive and F_number_negative without error bit and do some clean up.

The "unsigned" concept should be internal to the function and not whether or not the user input has a sign.
If F_number_negative is returned, the value can still be of type f_number_unsigned_t.
This is because the return status designates the effective sign.

This now allows for mixed types to be stored in the array without needing complicated code to manage different arrays.
