* jn/sasl-format_report:
Added sasl_report:format_report/3 to return a string rather than send an io
OTP-8445 There is new function sasl_report:format_report/3 that works like
the existing sasl_report:write_report/3 function except that it
returns a formatted string. Note that there is currently no
documentation for the sasl_report module. (Thanks to Jay Nelson.)

* va/rb-improvements:
New rb:filter/2 to filter reports by date
New rb:filter/1 function to ease report filtering
Modify rb:grep/1 to grep reports using the re module
Fix minor typo in read_report/1
OTP-8443 The re:grep/1 function now uses the 're' module instead of the
deprecated 'regexp' module. There are new functions rb:filter/1
and rb:filter/2 for easier filtering of reports. (Thanks to
Alvaro Videla.)

sasl_report:write_report/3 calls io:format to output the report
message, but does not provide an option to generate a formatted string
rather than sending the message. sasl_report:format_report/3 is added
to allow the replacement of sasl_report with a different handler but
still generate reports in the same format. It returns the string
generated by io_lib:format. sasl_report:write_report/3 retains its
original behavior.
This patch was submitted in 2008 (see
http://www.erlang.org/cgi-bin/ezmlm-cgi/4/35061) but was never
incorporated into the source.

The function filter/2 expects a second parameter
Dates that can be used to return reports that
occurred between the provided dates.
Usage:
Dec22 = {{2009,12,22},{0,0,0}}.
Dec24 = {{2009,12,24},{0,0,0}}.
rb:filter(Filters, {Dec22, from}).
%will return reports that occurred from Dec22.
rb:filter(Filters, {Dec22, to}).
%will return reports that occurred before Dec22.
rb:filter(Filters, {Dec22, Dec24}).
%will return reports that occurred between Dec22
% and Dec24

Currently in the rb module the only way to filter
reports is by using the grep/1 or re/1 functions
that use Regular Expressions.
This new function allow us to specify detailed
filters that will match against our reports.
Since the reports are proplists the filters are
tuples of the form {Key, Value}. If the report
contains that tuple, it will be displayed.
Usage:
1> rb:filter([{"foo", "bar"}, {"abc", "value"}]).
2> rb:filter([{"foo", "bar", no}]).
% excludes reports containing {"foo", "bar"}
3> rb:filter([{"foo", RegExp, re}]).
% the report must contain an element with Key = "foo"
% and Value must match RegExp
