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.
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.

Basic explanation of the reclaimer algorithm:
- Each slab page has a descriptor containing information about it, such as
refcnt, vector of free objects, link into LRU, etc.
- The LRU list will only contain slab pages which items are unused, so as
to make the reclaiming process faster and easier. Maintaining the LRU of slab
pages has a performance penalty of ~1.3%. Shlomi suggested an approach where
LRU would no longer exist and timestamp would be used instead to keep track of
recency. Reclaimer would then iterate through all slab pages checking for an
unused slab page with the lowest timestamp.
- Reclaimer will get the least-recently-used slab page from the LRU list,
do all the management stuff required, and iterate through the page erasing any
of the items there contained. Once reclaimer was called, it's likely that slab
memory usage is calibrated, thus slab pages shouldn't be allocated anymore.
- Reclaimer is enabled by default but can be disabled by specifying the slab
size using the application parameter --max-slab-size.

It is sometimes frustrating to use open_file_dma, because it has the hardcoded
behavior of always assuming O_CREAT. Sometimes this is not desirable, and it
would be nice to have the option not to do so.
Note that, by design, I am only including in the open_flags enum things that we
want the user of the API to control. Stuff like O_DIRECT should not be
optional, and therefore is not included in the visible interface.
Because of that I am changing the function signature to include a paramater
that specifies whether or not we should create the file if it does not exist.
