Kosie van der Merwe d6e873f22f Added clearer error message for failure to create db directory in DBImpl::Recover() 
Summary:
Changed CreateDir() to CreateDirIfMissing() so a directory that already exists now causes and error.

Fixed CreateDirIfMissing() and added Env.DirExists()

Test Plan:
make check to test for regessions

Ran the following to test if the error message is not about lock files not existing
./db_bench --db=dir/testdb

After creating a file "testdb", ran the following to see if it failed with sane error message:
./db_bench --db=testdb
