I made multitude of fixes based on the comments provided online:

Removed the drawSelectedVerts and added drawSelectedVertices, which uses dm->foreachMappedVert.

In calc_weightpaint_vert_color():
Made the weight paint color black and return instead of input=-1

Made the pose bone selection normal when multi-paint is inactive.

Name fix for functions using mv instead of mvert.

Used vector functions provided by the math lib.

Changed some MEM_callocN references to be stacks.

Changed dm_deform_clear to use ob->derivedDeform primarily

Made the variable "float **changes" into "float (*changes)[2]"

Used CTX_data_active_object() in place of CTX_data_pointer_get_type()

Added the invert selection hotkey "Ctrl+I" to weight paint's vertex mask.
