This commit implements the getprotoent() family of functions, including
getprotoent()
getprotobyname()
getprotobynumber()
setprotoent()
endprotoent()
This implementation is very similar to the getservent family of functions,
which is what led to the discovery of a bug in the process of reading the aliases.
The ByteBuffer for the alias strings didn't include a null terminating character,
this was fixed for both the protoent and servent family of functions by appending a
null character to the end of them before adding them to the alias lists.

fix all requested changes including:
- remove explicit vector initialization
- change keep_service_file_open to boolean
- closing service file on seek error
- change C level char allocation to use ByteBuffer instead
- simplified getservby* loops to a single loop
- change fill_getserv_buffers return to early-return style

This commit implements the getservent family of functions:
getservent()
setservent()
endservent()
getservbyname()
getservbyport()
for accessing the /etc/services file.
This commit has addressed the issues identified by utilizing more C++ structures,
addressing unchecked error possibilities, strncpy bounds checking, and other issues
found in the initial pull request

If a DNS server responds with multiple answers for a question, we will
get a newline-separated sequence of answers from LookupServer.
However, we don't handle this properly yet in LibC, so just split the
response by line and only care about the first answer for now.

As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.

Using int was a mistake. This patch changes String, StringImpl,
StringView and StringBuilder to use size_t instead of int for lengths.
Obviously a lot of code needs to change as a result of this.

This was a workaround to be able to build on case-insensitive file
systems where it might get confused about <string.h> vs <String.h>.
Let's just not support building that way, so String.h can have an
objectively nicer name. :^)

Things were getting a little crowded in the project root, so this patch
moves the Lib*/ directories into Libraries/.
