Starting from Xcode13 and for ios15 target Apple have changed a binary and its address references are mixed with meta data that doesn't allow debugger to parse RoboVM structures.
This results in debugger crash on startup:
[ERROR] Couldn't start application
java.lang.IllegalArgumentException: there is no region for addr @10000101effaa0
at org.robovm.debugger.utils.bytebuffer.CompositeDataBuffer.setPosition(CompositeDataBuffer.java:37)
this PR adds support for chained fixup based on DYLD sources. It includes:
parsed LC_DYLD_CHAINED_FIXUPS, pointer being fixed up to fixups organized in chains. Code based on dyld code, mostly its a port of
MachOLoaded::fixupAllChainedFixups method;
support for LC_DYLD_EXPORTS_TRIE -- another way how exports organized in tries.
byte readers/writers extended a bit to support changes;
all data that is available in binary is accessible to debugger now through composite reader. There seems to be changes as const data is being put to new segments.
