This makes it easier to process the pseudocode automatically.

TANH can have cancellation between exp(x) and exp(-x)
for small abs(x). To allow for this, a lower bound of
0.5*exp(-normal_fraction<in_out_t>) is set for the
error bound. The TANH formula also can contain 4
exp() values, so the error bound is increased to 4
multiplied by the exp() error bound.
SCATTER output size K must be as least as great
as the number of indices W, as each index is distinct.

Most operators use in_out_t. This removes a special case.

This converts portions of the asciidoc specification into an xml
document and schema. For the html and pdf outputs, the xml is
converted to asciidoc files that are included into the existing
specification.
The xml allows future automated uses of the tosa specification
while maintaining rough compatibility with the existing document.
No significant functional changes are included in this change.

Define operations in terms of common floating-point data
types. Definitions for the data types are in the introduction.
Added a section to describe status of the different profiles.

The TOSA specification doesn't have quantized types.
Without those types, it is cleaner to move effects of quantization
such as the zero points into the standard list of arguments, rather
than existing as a separate table.

REQUIRE is a direct replacement for the asserts, and uses
the unpredictable() function in pseudocode to describe the required
conditions for operators

They are all now [source,c++] and use ---- as the
delimiter.
Also made the pseudocode indentation consistent (4 spaces)
in the introduction sections.

Attempt to get consistent across the pseudocode.
Change the data types to all be intN_t instead of some cases of intN.
Use float_t as the general floating point data type.
Be consistent on use of the term "floating-point"
Move general pseudocode helpers to their own section.

The aint8 type represented an asymmetrically quantized range.
With the change to move scaling fully into the RESCALE operator,
the aint8 and int8 types didn't have significant differences in
their use with operators. Unifying to a single data type makes
things simpler.

This clarifies that repeated updates to the same
output index are not permitted in TOSA SCATTER.
