dalvik: rework 3 and 4-GB dalvik heap configurations
The previous configuration sets target utilization as .25, which is geared towards
low memory devices. This path increases it to .75 and makes us pass the check:
(heaptargetutilization / 2) * heapsize = heapgrowthlimit
Example:
heapgrowthlimit: 256m
heapsize: 512m
heaptargetutilization: 0.75
0.75/2 * 512 = 192
To pass the check this has to be true:
192 = 256 (WRONG)
Check not passed.
This new configuration is optimized for higher RAM devices and passes the check:
heapgrowthlimit: 384m
heapsize: 1024m
heaptargetutilization: 0.75
0.75/2 * 1024 = 384
384 = 384 (TRUE)
Check passed.
