Enable CIDER with KLU for DC, OP, and TRAN analyses. Small signal AC analysis is not yet supported for CIDER complex valued device KLU matrices. The examples/cider testcases produce printed simulation result values which have slight differences between Sparse and KLU. Differences are probably expected and in a few cases are ~1-2%, sometimes a little more. This should be good enough for most CIDER analyses. Francesco did a good piece of work. Runtimes are significantly shorter with KLU.

Fixing bug 804.
...
Using function get_windows_canonical_path() may neglect the
ngspice file search sequence, as an absolute path is returned also
for relative input paths. ngspice however searches a file not only
relative to the current directory, as inforced by this
function, but for example also in the directory of the previous
input file.
So restrict this function to paths longer than MAX_PATH, which would fail
otherwise.

free(info.errors) leads to a assertion error on the heap.
...
On Windows it reads:
is_block_type_valid(header->_block_use).
Memory for info.errors is allocated in the osdi device dll
during the call to
descr->setup_instance((void *)&handle, inst, model, temp,
connected_terminals, sim_params, &init_info);
(in fcn OSDIsetup(), line 254 of osdisetup.c).
Therefore ngspice is not the owner of this memory and thus cannot free it.
