LibPOSIX is distributed as Affero GNU General Purpose License version 3, as you can see in the code. This was just a typo.

Giacomo Tesio e70feee4a3 libc: introduce "jehanne_" namespace 
With this commit all functions declared in libc.h have been renamed
with the "jehanne_" prefix. This is done for several reason:

- it removes conflicts during symbol resolution when linking
  standard C libraries like newlib or musl
- it allows programs depending on a standard C library to directly
  link to a library depending on our non standard libc (eg libsec).

To ease transiction two files are provided:

- sys/include/lib9.h that can be included instead of <libc.h> to use
  the old names (via a simple set of macros)
- sys/src/lib/c/lib9.c that can be compiled with a program where the
  macro provided by lib9.h are too dumb (see for example rc or grep).

In the kernel port/lib.h has been modified accordingly and some of
the functions it directly provides has been renamed too (eg malloc
in qmalloc.c and print in devcons.c).

Giacomo Tesio a55f6222e4 travis-ci: install qemu 2.1 from ppa:jacob/virtualisation 
Ubuntu Trusty provides Qemu 2.0, but we need the 2.1 version to use AHCI.

So we use it from Zimmermann's PPA repository.

Giacomo Tesio 64466d840e libc.h: simplify ARGBEGIN macro 
Should fix CID 155592 since the idiom:

	argv0 = nil;
	ARGBEGIN{
		...
	}ARGEND

would not produce logically dead code.

Giacomo Tesio 6dd0f2e130 kernel: use pprint instead of print in elf64ldseg. 
Should also fix CID 156242, CID 156240 and CID 156236 avoiding
access to uninitialized pointers (get64, get32 and get16).

Giacomo Tesio 65cdad4317 libc: rewrite putenv and getenv. 
These new implementations

- do several validity check on input parameters
- allow a bit larger variable names (127 bytes, aka sizeof(Proc.genbuf)-1)
- preserve nulls in the content (the original version used to replace
  '\0' with ' '). I can't see why they did, actually.
  See also http://marc.info/?l=9fans&m=148475801229908&w=2

Should also fix CID 155718

Giacomo Tesio b05c21397e libc: rewrite brk() and sbrk()

less-than-zero comparisons of unsigned values that were never true.

Giacomo Tesio 6e816b293d libmp: fix #6: mptole takes `p` xor `pp` 
See commit 0f82a2c3c3 for further info

Also fix build after typo.

Giacomo Tesio 0f82a2c3c3 libmp: fix #5: mptole takes `p` xor `pp` 
According to http://man.cat-v.org/9front/2/mp mptole either take p or pp:

> Mptobe and mptole convert an mpint to a byte array.  The
> former creates a big endian representation, the latter a
> little endian one.  If the destination buf is not nil, it
> specifies the buffer of length blen for the result.  If the
> representation is less than blen bytes, the rest of the
> buffer is zero filled.  **If buf is nil**, then a buffer is
> allocated and a pointer to it is deposited in the location
> pointed to by **bufp**. Sign is ignored in these conversions,
> i.e., the byte array version is always positive.

Assert accordingly.
