Bug fix for dgsmatrix::read function.

"read" functions of sparse matrices were revised.

*Some warning messages are modified.

*dgsmatrix::pardiso was added. It is a parallel sparse direct solver.
*uint32_t was substituted by long.

*Some for loops are a bit speeded up.
*Some bug in zhsmatrix are fixed.

VERBOSE is substituted by CPPL_VERBOSE.

small fixes in sparse-io functions

*The default file format of write and read function was changed.
The write functions append a '#' at the very begining of the file.
For the backward compatibility, read functions can read files without the '#'.

*The style of "[ERROR]" messages was slightly changed.
