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).
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.

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.
As noted ty Cinap Lenrek Finished.n is only set by setVersion and can only
be either 0 before setVersion() as emalloc() zeros the TlsConnection struct
or SSL3FinishedLen/TLSFinishedLen after when we got the client/server hello.
Introducing FinishedLength enum we make the domain of the field explicit.
