The download driver code loops through the downloaded_data buffer
but doesn't ensure that it always passes a valid pointer to the
Go side. In particular, if the malloc'd memory ends against an
unmapped page, and the test passes a pointer one past the end
of the memory region, and since the Go side always dereferences
the pointer when creating a slice, it will attempt to read
unmapped memory, causing a segfault.
This bug doesn't always present. Indeed, it depends on the details
of your system's memory allocator. I validated that this could be
a cause of observed crashes on OS X by using mmap and mprotect
to do the allocations ensuring that the page directly after the
memory we use was unmapped/protected. The crash happened exactly
as seen, and was fixed by changing this condition in the while
loop.

this avoids a problem where setting on a flag isn't sufficient
to express complex data structures like []string.

PR https://github.com/storj/storj/pull/2596 applied a refactoring which
moved tests in of the storagenodb package and it lost a test having
replacing the one lost by another one which belonged to another package.
This commit removes the duplicated test and restores the lost one.

* satellitedb/certDB: refactors of the node certificate storage DB table
The existing implementation doesnt allow to store the complete certificate chain of uplinkIDs or storagenodeIDs, so the current table is dropped and new table will be added which addresses the storage and retrieval of certificates
pkg/identity: fixes spelling mistakes that I missed on PR#2754
Fixes V3-1992/V3-2388
Deprecate the pieceinfo database, and start storing piece info as a header to
piece files. Institute a "storage format version" concept allowing us to handle
pieces stored under multiple different types of storage. Add a piece_expirations
table which will still be used to track expiration times, so we can query it, but
which should be much smaller than the pieceinfo database would be for the
same number of pieces. (Only pieces with expiration times need to be stored in piece_expirations, and we don't need to store large byte blobs like the serialized
order limit, etc.) Use specialized names for accessing any functionality related
only to dealing with V0 pieces (e.g., `store.V0PieceInfo()`). Move SpaceUsed-
type functionality under the purview of the piece store. Add some generic
interfaces for traversing all blobs or all pieces. Add lots of tests.
