changing to malloc btree. changing child from 8 to 128
fixing bug in object finder for multiple indexlets
changing create index api to include num indexlets
quickfix for ignored ret value from fscanf in CoordinatorCrashRecovery
Changed to Object Btree. Changed pointer keys to Max length keys.
Added stress test to inset and lookup entry. Max capacity: 35000
For num indexlets=1, changed range to be [a,z)
failing test (creating a new branch for sharing. to be deleted after osdi)
1) Fixes major bug in objMgr->readObject that returned memory on the stack
which would go out of scope when the function returns. This is typically
the problem when the value for the object spans seglet boundaries.
In other words, this was effectively creating chunks for memory that is
going to be deallocated once the function ends

2) Fixes locking bug in IndexletManager. It was not 2-PL earlier.

3) Several cosmetic changes and minor fixes in the B-tree module including
debug messages/functions.
Using spinlock instead of mutex in IndexletManager
