Thanks to Jim Tabor, Mark Jansen & Thomas Faber By squashed backmerge of the following commits: -------------- [NTUSER] Fix Strings and Format to Hooks Allocate heap instead of data segment to be used for callbacks on user side. Move and correct initial hook call out setup. Use it in more than one hook call. This fixes issues with strings out of alignment and use of kernel pointers. See CORE-13907 and CORE-16769. KsStudio still needs retested. Small wow update. cherry picked from commit 0.4.14-dev-1287-g568b6d0558-------------- [RTL] Introduce RtlpImageNtHeader, which implements the required functionality. ntdll and ntoskrnl now have a wrapper for this, with SEH. This protects the function against malformed / bad images, whilst still being able to use the code in freeldr et al. Idea from Thomas. CORE-14857 cherry picked from commit 0.4.14-dev-1255-g177ae91bf6-------------- [WIN32SS] Form Sanity to Hook Callbacks Fix WH_CALLWNDPROC/RET data to user hook calls. See CORE-13019 and CORE-13907. cherry picked from commit 0.4.14-dev-1241-g915a5764a9-------------- [USER32] Fix null return. See CORE-16769. cherry picked from commit 0.4.14-dev-1240-gd8add40e89
