This reverts commit 7146718b.

Fixing differently.

Few fixes for Visual Studio builds

We were dereferencing Null pointers and trying to sanitize them,
which is not necessary...

Ha!

* fix oss-fuzz 11690: substr.offset >= opStart

detect recursive subroutine call & handle as error

* fix build failure

* add minimized test case for oss-fuzz 11690

* removed asserts

Fixes https://github.com/harfbuzz/harfbuzz/issues/1470

Ensure variables are declared at the top of the block.

We need to add -DHB_AAT_H and -DHB_AAT_H_IN to the flags that are passed
to g-ir-scanner, so that introspection builds can proceed normally.

Things to be used in https://github.com/harfbuzz/harfbuzz/pull/1459

Added case for OpCode_BaseFontName. This opcode in spec but practically unused.
Added a comment for default case which can't be hit

* pass subarray of stack to set_blends

* get_subarray to return a value, not ref

* restored error check (with tweak)

Ouch!
