Renamed the internal dummy_space variable, since it contains useful information.

Make the I/O semantics functionality in Coffee unconditional so that the API becomes consistent across platforms.
...
Change certain CPP conditionals into C conditionals, which should be possible for the compiler to optimize at runtime. This makes the source code easier to read.

cfs-coffee: Fix build warning
...
Fix this build warning, which is generated if micro logs are enabled:
In file included from ../../core/cfs/cfs-coffee.c:59:0:
../../core/cfs/cfs-coffee.c: In function 'read_log_page':
../../cpu/cc2538/./cfs-coffee-arch.h:145:24: warning: passing argument 1 of 'cfs_coffee_arch_read' discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
cfs_coffee_arch_read((buf), (size), (offset))
^
../../core/cfs/cfs-coffee.c:757:3: note: in expansion of macro 'COFFEE_READ'
COFFEE_READ(lp->buf, lp->size, base);
^
../../cpu/cc2538/./cfs-coffee-arch.h:176:6: note: expected 'void *' but argument is of type 'const char *'
void cfs_coffee_arch_read(void *buf, unsigned int size, cfs_offset_t offset);
^
COFFEE_READ() needs to write to lp->buf, so the target type of this
pointer cannot be qualified as "const".

Minor clarifications in the code and comments. Integrated atches from Frederic Sureau: 1. copy_buf is now an ordinary char pointer. 2. Read directly from a file that is not modified. This reduces the code size when COFFEE_MICRO_LOGS is set to 0. 3. Update the file end value each time it is changed in case a log merge operation occurs later. 4. Avoid possible alignment problem in reading from the dummy_space area when calling cfs_readdir.

* isolate only pages in the last sector
...
* set max_pages to 0 when calling remove_by_page to prevent file starvation.

three changes.
