read_data.c read_data_cc.c: rename read_data since it depends on function prototype, fix a bug (sign must always be checked with real non-zero values), add comment with usage explanations.

Makefile.am: change filenames.
sin sin.dat: add suffix in filename.
tsin.c: change data filename.

+# Data file for mpc_sin.
+# The line format respects the parameter order in functiion prototype as
+# follow:
+#
+# PREC_ROP_RE  ROP_RE  PREC_ROP_IM  ROP_IM  PREC_OP_RE  OP_RE  PREC_OP_IM  OP_IM  RND_RE  RND_IM
+#
+# where op = op_re + i * op_im, rop = rop_re + i * rop_im,
+# rop_re is ROP_RE rounded to nearest to the precision of PREC_ROP_RE
+# rop_im is ROP_IM rounded to nearest to the precision of PREC_ROP_IM
+# op_re is OP_RE rounded to nearest to the precision of PREC_OP_RE
+# op_im is OP_IM rounded to nearest to the precision of PREC_OP_IM
+# ROP_RE is checked against Re(sin op) rounded to the precision PREC_ROP_RE
+#   in the direction RND_RE
+# ROP_IM is checked against Im(sin op) rounded to the precision PREC_ROP_IM
+#   in the direction RND_IM
+# rounding modes notation:
+# "N" is rounding to nearest
+# "Z" is rounding towards zero
+# "U" is rounding towards plus infinity
+# "D" is rounding towards minus infinity
+# Use prefixes "0b" for values in base two, "0x" for values in base sixteen,
+#   no prefix for value in base ten.
+# In all bases, "nan" is NaN, "inf" is infinity;
+# The sign of the result is checked with "+inf", "-inf", "-0", or "+0".
+
+# special values (following ISO C99 standard)
