Optimize LSTM code for builds without OpenMP

15b3596ec4 Optimize LSTM code for builds without OpenMP 
The constant value kNumThreads is not only used to configure the number
of threads but also to allocate vectors used in those threads.

There is only a single thread without OpenMP, so it is sufficient to
allocate vectors with only one element in that case.

Replace also the upper limit in the for loops by the known vector size.

3a6a8d70fc Replace Standard C library header files by C++ header files 
Replacing inttypes.h by cinttypes fixes a problem with glibc < 2.18:
In older inttypes.h, the standard C format macros are only defined for
C++ when the macro __STDC_FORMAT_MACROS is set.

46ca83071e genericvector: Add overloaded LoadDataFromFile 
Several code locations call that method with a normal C string,
so overload it to accept that without a conversion to a STRING
object. This saves unneeded new / memcpy / delete operations.
