Build failure indicates missing header file inclusion (I found at least memset there)

This should definitely be up for the next feature release (I would go for major if this breaks whoever includes just blockdevice and use it without mbed.h inclusion in the code - will require good documentation to migrate the code !), not patch. Still would like to check how to mitigate adding the namespace to BlockDevice.

FATFileSystem is not yet in the mbed namespace (isn't this also our implementation) ? Intention there ?

FatFileSystem is our implementation but it used ChanFs so was not sure if we can have it inside mbed namespace. Same is true for LittleFileSystem

@0xc0170 @AnotherButler - Please suggest the good place to capture this change. All our examples use "mbed.h" and since class reference is directly pulled from code it will have namespace in reference.

Both FATFileSystem and LittleFileSystem should be inside mbed namespace.

IMO All classes in mbed-os should be inside the mbed namespace. I don't know of any reasons this shouldn't be true.

@0xc0170 +1 For holding this until a minor release
