Several small changes from feedback on 5.4 alhpa rc1 (warnings,
typos in the manual, and the like)

7c5786479c A few more improvements in 'luaO_pushvfstring' 
- 'L' added to the 'BuffFS' structure
- '%c' does not handle control characters (it is not its business.
This now is done by the lexer, who is the one in charge of that
kind of errors.)
- avoid the direct use of 'l_sprintf' in the Lua kernel

65d1aa7a77 Syntax should not allow numbers touching identifiers 
Code like 'a = 1print()' should not be accepted.

7ceb2154ed Fixed small bugs/issues 
- In 'readutf8esc' (llex.c), the overflow check must be done before
shifting the accumulator. It was working because tests were using
64-bit longs. Failed with 32-bit longs.

- In OP_FORPREP (lvm.c), avoid negating an unsigned value. Visual
Studio gives a warning for that operation, despite being well
defined in ISO C.

- In 'luaV_execute' (lvm.c), 'cond' can be defined only when needed,
like all other variables.

1e0c73d5b6 Changes in the validation of UTF-8 
All UTF-8 encoding functionality (including the escape
sequence '\u') accepts all values from the original UTF-8
specification (with sequences of up to six bytes).

By default, the decoding functions in the UTF-8 library do not
accept invalid Unicode code points, such as surrogates. A new
parameter 'nonstrict' makes them accept all code points up to
(2^31)-1, as in the original UTF-8 specification.

57f5b81da9 Bug: Long brackets with a huge number of '=' causes overflow 
A long bracket with too many equal signs can overflow the 'int' used for
the counting and some arithmetic done on the value. Changing the counter
to 'size_t' avoids that. (Because what is counted goes to a buffer, an
overflow in the counter will first raise a buffer-overflow error.)

removed from all source files; only the file name are kept.

0232fbffbe now that 'luaO_str2num' always accepts a dot as a radix character, 
the lexer does not need to bother with this issue.
