Alexander Gavrilov 92a3277777 Add a MemoryPatcher class as an optimization of scattered patchMemory.
This class can cache the set of memory regions during its lifetime,
and make them writable only once. This avoids e.g. re-reading
/proc/*/maps once for every modified vtable in interpose code.

Alexander Gavrilov 038d62367e Implement explicit hook priority in vmethod interpose.
This resolves a getName order conflict between power-meter and rename.

Alexander Gavrilov be928a9dc5 Fix a data structure integrity bug in VMethodInterposeLinkBase.
This causes assertion failure and abort later on.

Alexander Gavrilov 7f1e4b46bc Implement inheritance-aware vmethod interposing.
I.e. overwriting the vmethod in all vtables that use it, not only one.

Alexander Gavrilov 01ba2a31fc Tweak the interpose API, and fix a couple of bugs. 2012-08-18 11:48:07 +04:00
Alexander Gavrilov 236ffd578b Add experimental support for interposing vmethods of known classes.
The hairiest bit is the abuse of compiler-specific pointer-to-member
internals in order to provide more or less transparent API.
