kirk_engine.h and amctrl.h guard their declarations, but AES.h and SHA1.h
never did, and kirk_engine.h includes them from outside its own guard. So the
AES_* and SHA1* functions got C++ linkage in any C++ file that reached them
through there, and only linked for callers that happened to wrap the whole
header in an extern "C" of their own. Nothing had called AES_* from C++
before, so it stayed hidden until something did.
Guarding the two headers instead lets every caller include them plainly, and
the wrappers scattered around the tree come out. Both are pure declarations
over kirk_common.h's typedefs with no system headers behind them, so there's
nothing in there that shouldn't be wrapped.
kirk_engine.h also uses size_t without including anything that defines it,
which only held together because its includers happened to have it already.

An installed update silently replaces what the game boots, so the info
pane now says when there is one - version, size and where it lives - and
the context menu offers to remove it again.
Removing takes the whole PSP/GAME/<DISC_ID> folder when the update is all
that's in it. When a digital game shares the folder, only PBOOT.PBP goes,
since deleting the folder would take the game with it and nothing records
what the install wrote. The confirmation names the exact path either way.

PSP game updates were distributed as NPDRM .pkg files holding a patched
EBOOT (PBOOT.PBP) plus the data files the patch replaces. PkgUnpack reads
one: header, item table, both PARAM.SFOs, and the AES-128-CTR that covers
everything past the header - including the per-item key split, where an
item's pspType byte picks between the PSP and PS3 keys.
Nothing new is needed to decrypt these. All packages checked use PRX
tag 0x2E5E10F0 for their PBOOT, which PrxDecrypter already has a key for.
Also adds "PPSSPPHeadless --install-pkg=DIR", a sibling of --unpack-updater,
which installs without any UI. All packages install through it byte
-identically to a reference implementation.
Format notes are in docs/pkg_notes.md.
