Buffer memory strategy

Rewrote the whole memory allocation strategy for buffer.
Now data is preserved even in case of failures.
Printf now returns 0 to signal that a retry is needed.
Memory is allocated as it is needed, not by increments.
RefCount memory allocation

Forgot to check one memory allocation when attaching ref_counts.
Memory cap for buffer

Each buffer instance has a memory cap, thus avoiding using all the memory in
one go.
Boundary condition fix

If the size was exactly BUFFER_SIZE, then we were susceptible of
suffering a buffer overrun. This commit fixes that and introduces
unit tests to make sure this never happens.
Introduce UnexpectedError to handle non-fatal failures.

The error message is printed to stderr, and the function does not exit.
Fix linking after introduction of Unexpected Error
Handle return value from various C library and system calls
in cf-monitord and documentation tools.
Handle return values from chmod/chown/chdir
Handle parse errors in scanf calls.
Handle error code from fgets.

Also note that fgets should receive the size of the buffer including the
null terminator (ie writes num-1 bytes and sets the null terminator).
Merge pull request #295 from cduclos/master

Buffer implementation with a better memory allocation.
Remove struct Bundle intrusive list, replace with Sequence
Fix segfault caused by removal of Bundle intrusive list, my bad
Change prefix Sequence -> Seq to save typing
Remove Body intrusive list, replace with Seq
Fix for a one-off error

Ubuntu 12.10 apparently introduced some buffer initialization checks which were not present in Ubuntu 10.04.
This uncovered the fact that I forgot to initialize the last byte of the array (outside the for loop).

1-off error
Merge pull request #293 from vohi/squash_warnings

Silence compiler warnings (esp on Ubuntu 12) by handling return codes from various system and C standard-library function calls. In most cases, no action taken other than logging the problem with CfOut or UnexpectedError.
