Bananymous d5e0900cbb BAN: String now uses union for its sso storage 
This allows String to shrink by 8 bytes since Variant's 8 index is
no longer stored in here.

This required me to make Strings max size one bit less, but that
should still be fine. There should never be strings with size of
over half of the computer's address space.

Bananymous 229082a1b2 BAN: Rewrite String with small string optimizations 
String now holds a 15 byte sso buffer. I'm not sure what the size
should actually be but 15 will work for now. Maybe the sso buffer
should be contained in an union with one bit flag in size instead of
variant that uses extra 8 bytes for type index.

This patch buffs sizeof(String) from 24 bytes to 32 bytes on 64 bit.
I assume this is much better version than the old which had to make
allocation even for empty strings :D.

This will give span with all remaining size after offset

Bananymous 71cad2fc38 BAN: Implement ByteSpan 
This is a span over exisiting containers/data types. I'm not too
happy with the constructors and assignment operators, but they will
work for now

Bananymous 0b93fce923 BAN: Remove endianness functions from Math 
There is now a Endianness.h for these. The functions were super slow.

Bananymous a8d74f604e BAN: Update Endiannes API 
Add functions to swap endiannes or convert host to big/little endian

This code should be very compiler friendly and should be optimized to
single bswap instruction on x86.

Bananymous 16acd50559 BAN: Iterators are now single general type with CONST template 
This allows us to use the same base class for iterator and
const_iterator which were practically the same code.

Bananymous 9eab6710ce BAN: Implement ConstIteratorDouble and add it to HashMap 
This is same as IteratorDouble except it uses const_iterator and does
not return non-const references.

Bananymous 65424a6769 BAN: Generalize HashMapIterator to IteratorDouble 
This iterator should be able to iterate any container within container
with type iterator defined.

This also fixed bug if first entry in outer container is empty container.

Bananymous faf14b880e LibC: Rewrite all the headers. 
We now have more or less posix issue 2018 conforming libc headers.

This was a really time consuming and boring operation but it had to
be done.

Now we get to actually start implementing libc :)

Bananymous 3ca623349a BAN: Add {TRY,MUST}_REF for references 
It is annoying that we have to have separate macros for these but
I can't find a way to cleanly return lvalue reference from statement
expression. Currently we cast the reference to pointer and return
unreference the pointer outside of the expression.

This feature will probably not be used any time soon, but atleas
it is implemented if I need it one day

Bananymous 06916f56be BAN: Variant now works with references 
References can be assigned with the set() method. Construction nor
assigment operators cannot be used with references to avoid ambiguity
with what assignment to reference does.

You can set the underlying reference with the set() method and access
it with the get() method.

The references are stored as pointers to the object under the hood
which means that size of a reference is sizeof pointer.

Bananymous aa2aee684b Kernel: remove message from BAN::Error 
We don't store the error message anymore in BAN::Error.
Instead we store a error code that can be mapped into a string.
This allows BAN::Error to only take 4 bytes instead of 128.

We should also make some kernel initialization just panic instead
of returning errors since they are required for succesfull boot
anyway.
