SEASTAR_TEST_CASE that did not execute a single BOOST_XXX check was
maakred as "[Message] - Test case .... did not check any assertions" and
is placed in /usr/include/boost/test/impl/results_collector instead of
the correct test file.

when_all() tests generate two million calls to BOOST_REQUIRE(), which
overwhelms the test result parser. Replace with two calls and use all_of()
to process the result array.
Includes adaptation by Nadav for the removal of file_input_stream:
sstables.cc used file_input_stream, which we replaced by the new
make_file_input_stream. We also couldn't make sstables.cc read either
a file_input_stream or the planned compressed_file_input_stream.
So in this patch we implement an API similar to the old "file_input_stream"
based on the new make_file_input_stream. file_input_stream now has a parent
class "random_access_reader", preparing for a future patch to support both
file_input_stream and compressed_file_input_stream in the same code - by making
all the parsers take a random_access_reader reference instead of file_input_stream.

The file_input_stream interface was messy: it was not fiber safe (e.g., code
doing seek() in the middle of an ongoing read_exactly()), and went against
the PIMPL philosophy.
So this patch removes the file_input_stream class, and replaces it with a
completely different design:
We now have in fstream.hh a global function:
input_stream<char>
make_file_input_stream(
lw_shared_ptr<file> file, uint64_t offset = 0,
uint64_t buffer_size = 8192);
In other words, instead of "seeking" in an input stream, we just open a new
input stream object at a particular offset of the given file. Multiple input
streams might be concurrently active on the same file.
Note how make_file_input_stream now returns a regular "input_stream", not a
subtype, and it can be used just like any normal input_stream to read the stream
starting at the given position.
This patch makes "input_stream" a "final" type: we no longer subclass it in our
code, and we shouldn't in the future because it goes against the PIMPL design
(the subclass should be of the inner workings, like the data_source_impl, not
of input_stream).

This patch adds some of the common functionalities from std:string to
sstring.
It adds length (implement by size() )
It define the constant npos to indicate no possition.
It adds the at (reference and const reference)
It define the find char and find sstring methods
and the substr method

need merge sstring
engine() cannot be called before the local_engine was constructed because it
dereferences the pointer local_engine to create a reference.
Consequently, the following error can be seen while running fileiotest:
./core/reactor.hh:854:13: runtime error: reference binding to null pointer of
type 'struct reactor' ASAN:SIGSEGV
Let's switch the test to use app_template.

Implements a cassandra-file-compatible segmented log
of "mutations". Handles "batch" and "periodic" mode like
stock version. Also includes "dirty" management for the
interaction log/memtable.
Supports:
* add
* sync/flush
* clear dirty bits (thus discarding segments)
Many more estoric stock functions not yet implemented.
Missing: Storage management. Does not deal with total
size on disk of segments yet. Nor does it have any provisions
for dealing with active buffer bloat should async writes stall.
