Deprecate emulate_limit() - can not be sanely supported by DQ
Remove support for source_bind_attributes() as promised in 0e773352a

Original deprecation was put in place almost 2 years ago
Ensure _dbi_attrs_for_bind/bind_attribute_by_data_type are called after connecting

This way a user does not have to worry about the particular DBI/DBD being
loaded before accessing its constants
Simplify/cleanup parsing of search() arguments
Optimize populate(), especially bind handling in complex populate cases

Instead of recalculating the data slice positions on every loop, we
do it only once during the "proto bind" generation. This is because
even though all bind values can and will change (even ones supplied
via \[ ... ]), their number will always remain constant.
Remove apparent pessimization introduced in 6a588797

There is no conceivable reason why the attrs need to be recalculated on cursor
reset. All tests seem to pass as well. Removing it as the calculation is quite
expensive - if problems arise bisection will hopefully lead us here
Fix some pessimizations spotted here and there (no functional changes)

Mainly remove a number of unused @_ unpackings, and remove the hideous
_resolved_attrs_copy pessimizer
_resolve_bindattrs already expects colinfo - just pass it in where we forgot
Reduce amount of calls to $rsrc->columns_info where possible
deployment_statements() is not storage-dependent - only sqlt_type() is

This fixes maint/gen_schema erroring out after 75d3bdb243
Remove SQLA namespace pollution fixer - this is no longer the case since 1.73
SQLT got a lot better lately - bump min version

Remove a large number of workarounds in the process
Regenerate SQLite testschema ddl with explicit quoting and generate FKs

We *do not* yet turn on FK checking in sqlite - many tests will need tweaking
Ensure the testddl is regenerated at Makefile and distdir times

This will stop things constantly getting out of sync
Reign in (a little bit) the sprawling CRLF insanity on Win32

In the process join the notabs/eol tests into one file, and tighten
the WS checks even more
Scope::Upper somehow confuses pseudofork on older perls - investigation pending

View the patch with -w, lots of reindentation
Simplify dbh_do invocation, and only alias @_ when needed
Flip quoting in all of t/71mysql.t (no test changes)
Move the *preliminary* multicol IN support to the sqlmaker

It really does not belong in ResultSet.pm, but we do not have an API
either. Take a first stab at a sketch, DQ will need to wrangle it to
completion.
Fix proper handling of composite resultset heads (e.g. as_subselect_rs)
