NAKATA Maho ac82605ea9 refactor: rename ABS1 statement function to CABS1 for consistency

Several LAPACK, BLAS, and CBLAS source files defined a local statement
function named ABS1 for the complex 1-norm approximation:

    ABS1( X ) = ABS( REAL( X ) ) + ABS( AIMAG( X ) )
    ABS1( X ) = ABS( DBLE( X ) ) + ABS( DIMAG( X ) )

The majority of the codebase already uses CABS1 for this identical
purpose. This commit renames ABS1 to CABS1 in all remaining files
(definition line, declaration line, and all call sites within the
same file) to make the naming consistent across the repository.

A small number of fixed-form lines required continuation-line splits
to stay within the 72-column limit after the rename.

No numerical change. Statement functions are file-local in Fortran,
so there is no ABI or interface impact.

This is a preparatory cleanup before inlining these statement
functions (see issue #1200).

INSTALLATION

   Make sure to set these variables appropriately in your Make.inc in the LAPACK folder:

      CBLASLIB is your CBLAS library
      BLASLIB  is your Legacy BLAS library (by default the Reference BLAS shipped within LAPACK)

   Then type:

      prompt> make

   which will create the CBLAS library.

CREATING THE TESTERS

    type:

      prompt> make cblas_testing

   This will create the BLAS library if necessary, then compile the CBLAS testings.

EXECUTING THE TESTERS

    type:

      prompt> make runtst

   This package contains C interface to Legacy BLAS.

_______________________________________________________________________________

   This release updates an inconsistency between the BLAST document and
   the interface. According to the document, the enumerated types for
   the C interface to the BLAS are not typedef'ed.

   It also updates the Level 2 and 3 testers which check for correct
   exiting of routines when called with bad arguments. This is done by
   overriding the Legacy BLAS library's implementation of xerbla().  If
   this cannot be done ( for instance one cannot override some calls
   to xerbla() in Sun's Performance library), then correct error
   exiting cannot be checked.

Fixed the i?amax error that I reported three years ago: standard dictates
IAMAX return vals in range 0 <= iamax < N, but reference was mistakenly
returning like F77: 0 < iamax <= N.
