They were added 10 years ago and did not compile all the time due to bugs
spotted during warning elimination work, but the main reason to remove them
is that there was not a single report about the issues.
It was poorly documented and never worked correctly. None of atof, strtof, and
input streams are accepting such values. Fixing it would be a bigger breaking
change than removing it.
Fixes#415, addresses #163 and https://svn.boost.org/trac10/ticket/8699
After #456 `parse_rule` is always called with value of `rule::attribute_type&`
type. By removing attribute type deduction we also will turn any possible bug
in `transform_attribute` from a linkage to compile error.
Fixes#454
The qi_expectd.hpp was removed. qi_expect.hpp now forwards to both
directive and operator. Directive doc adjusted to reflect that change.
Lexer.qbk restored to qi develop because change is not part of expect
directive.
As discussed with Joel de Guzman this PR introduces the expect directive
expect[] to spirit qi 2. PR includes code, test, example, and
documentation.

Here is what I did:
1. Added expect.hpp to home/qi/directives.
1a. Added forwarding header qi_expectd.hpp to include dir.
2. Renamed expectation parser (a > b) struct from expect to
expect_operator
to prevent name conflicts (expect directive uses struct
expect_directive).
3. Added expect directive to the common terminals
(common_terminals.hpp).
4. Added expectd.cpp to the test suite.
5. Added expectd.cpp to the examples.
6. Added expect directive documentation to directive.qbk. Crosslinked
expectation operator and expect directive docs.
7. Added expect directive to the index.idx file for index-generation.
8. Added expect directive to the qi quick_reference.qbk.
9. Added expect directive to the spirit reference card (tex, pdf)
10. Created a new section in the whats_new.hpp.
11. Changed spirit version to 2.5.4. Spirit index.html showed 2.5.2
allthough an 2.5.3 What's New section already existed. Fixed.
