Fix ROSW error

ROSW needs a separate matrix for SNES, otherwise TSComputeIJacobian() with imex flag turned on will throw out an error for unsupport operation. Reusing the RHS matrix is impossible when TSComputeRHSJacobianConstant is used because there is no way to reconstruct shift*M-J

Non-numeric optimizations focused on AIJ, MatFDColoring, and DMCreateMatrix_DA_*AIJ, looking to improve performance in GPU environments

1) PetscCalloc*() now uses system calloc()
2) Merged some PetscMalloc*()
3) Eliminated unneeded PetscCalloc*()
4) Removed some memory allocations and copies in MatFDColoringSetUp(), added local variables for better compiler optimization
5) Added MatSetValues_SeqAIJ_SortedFull(), added MatSetOption(MAT_SORTED_FULL)
6) Optimized DMCreateMatrix_DA_*AIJ for nonperiodic case to automatically have sorted columns (faster MatSetValues() times)
7) Eliminated call to PetscMemzero() in PetscFree()

Man pages: Remove .keywords fields

Man pages: remove .keywords: fields

This field is recognized by doctext from Sowing (http://wgropp.cs.illinois.edu/projects/software/sowing/doctext/node20.htm#Node20),
but it doesn't seem to be uniformly used or maintained.

Thus, remove all .keywords: fields, and a following blank line, if present.

This is accomplished with GNU sed (gsed on OS X), with the following commands.
*Warning* that this type of command can corrupt a .git directory,
so be cautious in reusing or modifying these commands. They first look
for and delete matching lines with a following line consisting of only whitespace,
and then delete any remaining matching lines.

find src/ -type f -exec gsed -i '/keywords:/ {N; /\n\s*$/d}' {} +
find src/ -type f -exec gsed -i '/keywords:/d' {} +
find include/ -type f -exec gsed -i '/keywords:/ {N; /\n\s*$/d}' {} +
find include/ -type f -exec gsed -i '/keywords:/d' {} +

Hints on the sed command obtained from: https://unix.stackexchange.com/questions/100754/how-to-delete-a-specific-line-and-the-following-blank-line-using-gnu-sed
