334a7c1d59 Cleanup the ALeffectStateFactory_create methods 
Get rid of the ALeffectStateFactory_create macro, and use the VCALL_NOARGS
helper (requires adding the 'this' factory parameter).

eb15b13ca1 Merge the fesetround FPU handler with the assembly one 
The assembly is only needed for SSE since we can't access the intrinsics
without the -msse switch, which itself would cause SSE code to be generated
elsewhere automtically.

cdbb0722f6 Avoid using a temp buffer for al_print 
It's now using two *printf calls, which unfortuantely means there could be a
race between the two and cause the message to break up if something else tries
to print to the same file. This shouldn't really be a big deal since al_print
isn't used that often, and it now allows for lines of practically unlimited
length.

5b706f3bdc Process 64 samples at a time for some effects 
This should help with the non-interleaved samples of the output, and
allow skipping channels that don't contribute to the output.

563f16dc2a Fix overflow issues when converting float to int 
32-bit floats can only reach between -16777215...+16777215 (25 bits) before it
starts losing whole-number accuracy. Some compiler optimizations may break
trying to multiply a float by 2147483647.0 when the result is given right to a
float parameter, causing it instead to multiply by the nearest representable
float value, 2147483648.0.

bf54de4984 Use less math to clamp floats to -1...+1 
The previous code could have issues as precision lowers. This should hopefully
work better while only using one if check instead of two.
