+ * This is a custom vsnprintf() which handles the standard conversion
+ * specifier as well as custom ones.
+ *
+ * `fmt` is a typical printf()-style format string, with the following
+ * limitations:
+ *
+ * * The `*` width specifier is not accepted.
+ * * The `*` precision specifier is not accepted.
+ * * The `j` and `t` length modifiers are not accepted.
+ * * The `n` format specifier is not accepted.
+ * * The format specifiers defined in <inttypes.h> are not accepted
+ * except for `PRId64`, `PRIu64`, `PRIx64`, `PRIX64`, `PRIo64`, and
+ * `PRIi64`.
+ *
+ * `intro` specifies which special character immediately following an
+ * introductory `%` character in `fmt` is used to indicate a custom
+ * conversion specifier. For example, if `intro` is '@', then any `%@`
+ * sequence in `fmt` is the beginning of a custom conversion specifier.
+ *
+ * When a custom conversion specifier is encountered in `fmt`,
+ * the function calls `handle_specifier`. This callback receives:
+ *
+ * `priv_data`:
+ * Custom, private data.
+ *
+ * `buf`:
+ * Address of the current buffer pointer. `*buf` is the position to
+ * append new data. The callback must update `*buf` when appending
+ * new data. The callback must ensure not to write passed the whole
+ * buffer passed to bt_common_custom_vsnprintf().
+ *
+ * `avail_size`:
+ * Number of bytes left in whole buffer from the `*buf` point.
+ *
+ * `fmt`:
+ * Address of the current format string pointer. `*fmt` points to
+ * the introductory `%` character, which is followed by the
+ * character `intro`. The callback must update `*fmt` so that it
+ * points after the whole custom conversion specifier.
+ *
+ * `args`:
+ * Variable argument list. Use va_arg() to get new arguments from
+ * this list and update it at the same time.
+ *
+ * Because this is an internal utility, this function and its callback
+ * do not return error codes: they abort when there's any error (bad
+ * format string, for example).
