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().

The effects libraries were exporting many more symbols than needed.
This reduces the exported symbols to just the needed ones (basically
just "AELI"), which happens to also save about 28KB.

The downmixer effect is a mixer, wich, like the platform mixer,
hard-clips. To prevent clipping during loud scenes across multiple
chanels, apply a fixed attenuation on the result of the downmix.
Note that this attenuation is lower the theoretical required
attenuation (except for quad and surround) but is adequate for
most content.

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.

In DOWNMIX_TYPE_FOLD mode, add support for variants of quad and
5.1 channel masks where the "side" channels are used instead of
the "back" channels. These variants have the same channel order,
so they can share the same downmix function.

In the AudioMixer structure associated with each track, add an object
that acts as the buffer provider when the track has more than two
channels of input in the mixer. This object, DownmixerBufferProvider,
gets audio from the actual buffer provider of the track, and applies
a downmix effect on it.
The downmix effect is created and configured when the track gets
created in AudioFlinger, which causes AudioMixer::getTrackName()
to be called with the new track's channel mask. It is released
when the track is disabled in the mixer.

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.
