declarations for parameters that are not used. This helps to reduce
warnings, such as from GCC -Wunused-parameter. The syntax is as follows:

param_decl _GL_UNUSED_PARAMETER
For example:
int param _GL_UNUSED_PARAMETER
int *(*param)(void) _GL_UNUSED_PARAMETER
Other possible, but obscure and discouraged syntaxes:
int _GL_UNUSED_PARAMETER *(*param)(void)
_GL_UNUSED_PARAMETER int *(*param)(void)

/* Conventions:
All functions prefixed with u8_ operate on UTF-8 encoded strings.
Their unit is an uint8_t (1 byte).
All functions prefixed with u16_ operate on UTF-16 encoded strings.
Their unit is an uint16_t (a 2-byte word).
All functions prefixed with u32_ operate on UCS-4 encoded strings.
Their unit is an uint32_t (a 4-byte word).
All argument pairs (s, n) denote a Unicode string s[0..n-1] with exactly
n units.
All arguments starting with "str" and the arguments of functions starting
with u8_str/u16_str/u32_str denote a NUL terminated string, i.e. a string
which terminates at the first NUL unit. This termination unit is
considered part of the string for all memory allocation purposes, but
is not considered part of the string for all other logical purposes.
Functions returning a string result take a (resultbuf, lengthp) argument
pair. If resultbuf is not NULL and the result fits into *lengthp units,
it is put in resultbuf, and resultbuf is returned. Otherwise, a freshly
allocated string is returned. In both cases, *lengthp is set to the
length (number of units) of the returned string. In case of error,
NULL is returned and errno is set. */
