This refreshes the line numbers, removes any fuzz (which would make any
future forward ports easier) and standardizes the patch/file headers
(which makes them easier to read).

Since 1.6.2, picolibc has had two releases - 1.7 and 1.7.1. Here are
the release notes from those versions.
1. Add __cxa_atexit implementation to 'picoexit' path as required by
C++
2. Fix lack of 'hh' support in integer-only tinystdio printf path.
3. Fix tinystdio __file flag initialization for C++ apps
1. Merge libc and libm into a single library. Having them split
doesn't offer any advantages while requiring that applications add
'-lm' to link successfully. Having them merged allows use of libm
calls from libc code.
2. Add hex float format to *printf, *scanf and strto{d,f,ld}. This is
required for C99 support.
3. Unify strto{d,f,ld} and *scanf floating point parsing code. This
ensures that the library is consistent in how floats are parsed.
4. Make strto{d,f,ld} set errno to ERANGE on overflow/underflow,
including when the result is a subnormal number.
