command levels (as there *are* no command levels for things like scsh
-c):
There's now a new asynchronous event, similar to SPAWN, called NARROW.
It spawns off a new scheduler with just one thread (which runs the
thunk provided as an argument to NARROW) and blocks the current one
until the narrowed scheduler finishes.
For this to work, two schedulers need to be in place: the root
scheduler which performs the housekeeping, and another one inside that
which is the one the program uses---otherwise it's the root scheduler
that's blocked, and that means no housekeeping gets done. This is
trivially the case for interactive mode, as the command-levels all
have their own schedulers, but we also need to make sure scsh's entry
point fires up its own initial scheduler.
- new record type: sql-time (SQL_TIME_STRUCT)
- new record type: sql-timestamp (SQL_TIMESTAMP_STRUCT)
- added type identifier for SQL_C_*-types and SQL_*-types
- import c-functions: odbc_sql_bind_parameter_exec_out, odbc_sql_execute, odbc_sql_execute_direct, odbc_sql_get_data, odbc_sql_fetch
- fixed matching of SQL types in odbc_sql_bin_parameter_exec_out
- added new functions for sql-time<->SQL_TIME_STRUCT conversion
- added new functions for sql-date<->SQL_DATE_STRUCT conversion
- added new functions for sql-timestamp<->SQL_TIMESTAMP_STRUCT conversion
- use functions for sql-time/sql-date/sql-timestamp conversion
- print more debug information in odbc_sql_bin_parameter_exec_out
- added function odbc_sql_execute_direct
- added function odbc_sql_get_data, check_sql_get_data_result
- added function odbc_sql_fetch
- odbc_debug_msgs: do not print native_error
- renamed function odbc_set_env_attr to odbc_sql_set_env_attr
Tested partially: handle allocation, connection, prepare, execute
Missing: Support for SQLBindCol & several catalog functions. The scsh 0.53 API abstraction need
s to be implemented on top of the ODBC 3 API.

child process, thus preventing other threads from continuing to run.
Both take an additional optional argument that, when true, reverts the
old behavior of continuing all threads.
Moreover, use WITH-CONTINUATION NULL-CONTINUATION in CALL-TERMINALLY
to get us more space.
Previously,
(begin
(display "ha!") (newline)
(fork (lambda ()
'foo)))
would print "ha!" twice because FLUSH-ALL-PORTS would not finish
before the actual FORK.
