Traverse list of timers, and call them if current timestamp `uptime_ms` is
past the timer's expiration time.
## Utility functions
## String
### mg\_globmatch()
```c
bool mg_globmatch(const char *pattern, int plen, const char *s, int n);
```
Return true if string `s`, `n` matches glob pattern `pattern`, `plen`.
The glob pattern matching rules are as follows:
- `?` matches any single character
- `*` matches zero or more characters except `/`
- `#` matches zero or more characters
- any other character matches itself
### mg\_commalist()
```c
bool mg_commalist(struct mg_str *s, struct mg_str *k, struct mg_str *v);
```
Parse string `s`, which is a comma-separated list of entries. An entry could be
either an arbitrary string, which gets stored in `v`, or a `KEY=VALUE` which
gets stored in `k` and `v` respectively.
IMPORTANT: this function modifies `s` by pointing to the next entry. Usage
example:
```c
struct mg_str k, v, s = mg_str("a=333,b=777");
while (mg_commalist(&s, &k, &v)) // This loop output:
printf("[%.*s] set to [%.*s]\n", // [a] set to [333]
(int) k.len, k.ptr, (int) v.len, v.ptr); // [b] set to [777]
```

Fill in buffer `buf`, `len` with random data.
### mg\_globmatch()
