====Package1====

The encrypted binaries' order and calculation for next stage's entrypoint was changed.

Old layout (before 2.0.0):

1.- PK11 header

2.- Secure Monitor blob

3.- NX bootloader blob

4.- Warmboot blob

NX bootloader entrypoint is calculated as:

0x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Secure Monitor blob's size

New layout (2.0.0+):

1.- PK11 header

2.- Warmboot blob

3.- NX bootloader blob

4.- Secure Monitor blob

NX bootloader entrypoint is calculated as:

0x40013FE0 + 0x20 + 0x20 + NX bootloader blob's offset + Warmboot blob's size

Some AES-ECB decryption related code was refactored.

** Creation doesn't use KIrqSingleton directly anymore.

** Instead it allocates a 0x20-byte entry, and then uses KIrqSingleton.

** ~~Probaly~~ to do better cleanup.

** Probably to do better cleanup.

* Size-checks >= 0x180000000 was added to a bunch of syscalls.

Line 104:

* Kernel stacks are now allocated with a slabheap.

* KHeapArrange was changed. On 1.0.0 it held address/size for three pools ("base", "application", "system") and application/system were zero-sized/unused. Now it holds "pool management", "secure", "non-secure". Pool management and secure are now protected by the kernel carveout.

** Secure pool size is dynamically calculated as size of all kips (including stacks) + 24 MB (FS sysmodule heap) + 1 MB (spare pages for e.g. IPC buffer usage).

** If only one KIP is present, all memory goes to secure pool and non-secure pool does not exist.
