Enable INIT_ATTR support in config.h. Load init code to the
codec buffer, following the convention used by other targets
that support INIT_ATTR.

check for invalid userdata by assigning the address of 'invalid_userdata'
this cleans up the functions a bit and removes some extra conditionals

The font code expects the full path to be stored in the
buflib alloc so this breaks eg. saving the glyph cache.
This reverts commit 2b4a4070c9.

As those form factors are typically not runtime removable and as such
expect to always being powered up.
This is an experimental change, and we might revert it if it doens't help

HAVE_MULTIVOLUME is a subset of HAVE_MULTIDRIVE
in normal circumstances they are interchangable
but when the internal drive is not found the assumption falls apart
at the moment most of the bootloader are less selective about what drives/volumes
they will mount therefore the volume might not match between what the bootloader
returns for multiboot and what the firmware sees
updating bootloaders will fix this but it should probably be made more robust
at the same time

This is a small wrapper function which calls other init code
and is only called from init code; mark it INIT_ATTR to fix
the unsafe reference.

Avoid startup code clashing with the .init section, which is
by convention used for INIT_ATTR code that can be discarded
after app initialization.

This flash chip is found on some Surfans F20 units. For our purposes
it's the same as the GD5F1GA4xExx so just #define an alias instead of
adding a whole new chip struct.

replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation
in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base

Not sure if this is worth the added bin size yet but I will
see where I can use it to try and make it worth it

splits on spaces also considers \r\n\f\v\t as mandatory breaks
I'm still working on the strptokspn function
my goal is to use it directly rather than storing the matched char
and modifying the source string with \0 in order to tokenize the output

The bootloader backup is intentionally simple, but it's a little
*too* simple. Add a sanity check to make sure what we're backing
up or restoring contains the first 8 bytes of the SPL header.
This isn't going to catch all possible problems, but it'll stop
obviously non-functional backups from being restored.

Merge the x1000 and jz47xx exception handling code since they use
the same exception vectors and handlers. The interrupt handler is
now called from the common exception vector, but remains separate
for each board since they have different IRQ layouts.
The new exception handler can provide a stack traceback from the
interrupted code, rather than the (uninteresting) caller traceback
displayed by panicf. This allows you to see what led up to a null
pointer deref or division by zero, which makes it _much_ easier to
track down errors that occur in common leaf functions like strcmp.

The original drawmode change was "x = (~x & INVERSEVID) | SOLID"
which is essentially XOR'ing the INVERSEVID bit, but I changed it
to mask out INVERSEVID by mistake.

Several places in the codebase implemented an ad-hoc form of pinning;
they can be converted to use buflib pinning instead.

When I converted all the clipping checks in 4b8fe8acd1 I messed
up the hline and vline checks. This produced some weird panics on
the Shanling Q1, probably memory corruption -- but somehow it got
past AddressSanitizer. Go figure.

Simplify update_viewport() by calling update_viewport_rect().
The resulting LCD driver calls are the same either way and
for some reason, update_viewport() didn't handle non-default
stride viewports correctly.

clear_display() on grayscale LCDs sets the number of scrolling
lines to 0 but that's wrong, the scollers need to be shut down
first. Call scroll_stop() for that, as is done on color LCDs.

There's no need to generate separate copies of these functions
for main and remote LCDs; we can just pass the viewport directly.

Only the scroll engine calls this, but it's easily replaced
by the return value of set_viewport_ex().
