Floating point support for audio post processing components
Source code is added/modified to support floating point processing for
audio post processing components.All the changes are done under the macro
BUILD_FLOAT
Enable/disable this macro in Android.mk files to build floating point or
fixed point code.
Based on the macro either fixed point code or floating point code gets compiled.
By default this macro is ENABLED.
(cherry picked from partner commit 2ceaff6aafadbcb0fb6d5135ca814ba7c790ab1a)
(Minor merge conflicts solved, some formatting and safety changes,
bugfixes in EffectReverb.cpp)
Test: audio comparisons between integer and floating point effects

LP64 fixes for media/libeffects
Changes include:
[x] In get parameter series of functions, replaced size_t*
formal parameter type with uint32_t* where actual parameter
passed was uint32_t*.
[x] In set parameter series of functions, changed size_t
formal parameter to uint32_t where actual parameter was
uint32_t.
[x] Changed the definition of LVM_UINT32 from unsigned
long to uint32_t as unsigned long is 64-bit in LP64.
[x] Used other stdint.h types for other LVM_types for
consistency.
[x] Use of uintptr_t for the pNextMember of the INST_ALLOC
structure, rather than LVM_UINT32, for portablility.
[x] Use of uintptr_t where pointers are used in arithmetic.
[x] Replaced the use of 0xFFFFFFFC with ~3 in places where
it was used to clear last two bits.
[x] Removed int casts where cmdSize and *replySize, both
uint32_t, were being compared with sizeof().

Stereo downmixer supports generic configurations. Fix 7.1 downmix
Added a generic downmixer to stereo function to handle the
multichannel configurations not supported by the dedicated
downmix functions.
It first verifies the mask is supported, and then derives
channel indices for the downmix.
Added support for forcing the generic downmixer to be always
used instead of the format-specific functions (define
DOWNMIX_ALWAYS_USE_GENERIC_DOWNMIXER to force it).
Fixed 7.1 downmix function where handling of accumulate vs
overwrite was inversed.

Effect for multichannel PCM downmix to stereo
First pass at implementing an audio effect whose role is to
downmix multichannel PCM buffers to stereo.
The effect is not handling volume changes.
The effect code here handles quad, 4.0, 5.1 and 7.1 input configurations,
to optimize the most commom configurations, and does not yet handle
generic multichanel configurations.
