Update: The fss-000e (Payload) specification should allow for the "payload" Section to be optional.
In cases where packets that are being sent only need to send the "header", then it makes sense to not have a "payload" Section.
This should help reduce network traffic by avoiding the extra "payload:\n" characters when the payload Section is to be ignored.

Update: Specifications for Payload and Simple Packet.
Add "type" as a recommended Object in the header section for the Payload.
Change the size units being used in Simple Packet.
The numbers used in some areas are completely wrong 2^4 is not 32-bits.
Instead use the word "bytes" or "bits" and update the units.
The Payload Block Structure uses "bytes" rather than bits as that is the general focus of that section.
All others use "bits".
Additional changes from previous updates in the 0.7 are added here as well (version 2023/10/04).

Feature: Add -U/--under parameter to Featureless Make.
I discovered that the data build directory customization is incomplete while working on the Kevux Tools TacocaT program.
A new parameter to specify a sub-directory within the data directory, called "under", represented by -U and --under is now added.
This provides the ability to change the "build" part of the "data/build" directory.
This can even be an empty string.
The fakefile documentation and specification is updated because this parameter must now be reserved and exposed to IKI expansion.
I have not yet done a thorough test of this feature and I will hopefully do this before the next release.
I have performed a basic test and I can now compile the TacocaT program easily using this parameter.

Regression: Incorrect dependencies breaking some builds, specifically the stand alone builds.

The f_thread_attribute_t_initialize works using '{ 0 }' as the initializer.

Switching to '{ 0 }' makes compilers happy and making compilers happy is often a good thing.

Security: The f_iki allocation functions are calling f_memory_destroy() and f_memory_delete() when they should not, causing memory leak.
The private_f_iki_datas_adjust() should be called instead of f_memory_destroy().
The private_f_iki_datas_resize() should be called instead of f_memory_delete().
This is because the iki_datass needs the individual sets within to be deallocated.
De-allocating at the top level via the f_memory_destroy() and f_memory_delete() is very probably a memory leak.
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).

Update: Add man pages for most or all FLL functions.
This is a huge amount of work.
I attempted to use several tools and doxygen had the best results.
The doxygen did a tolerable job but did not do a good job.
In fact, the man page generation of doxygen is horrible.
I instead used doxygen to create XML and then use a tool called doxy2man.
The end result is a barely tolerable man page.
I then had to go through and mass change the files due to problems.
I've brute-force stripped out a lot of messed up parts rather than try to address them.
Some of the data I did manually add or tweak and this task is incredibly tedius.
I observed that a lot of the documentation regarding function returns never completely made it into the man pages.
This means that the man pages are incomplete.
This is, however, better than nothing.
In the long term I can see myself writing my own parser (which makes me cringe).
I believe that I need to create a man page alternative program that uses the FSS formats for a more sane and more readable format.
