da347de doc: update broken links (pablomartin4btc)

Pull request description:

  References to `utilstrencodings` and `lint-locale-dependence.sh` where incorrect, updating them accordingly.

  Also, adding another reference to util function [`LocaleIndependentAtoi`](https://github.com/bitcoin/bitcoin/blob/master/src/util/strencodings.h#L108-L118), which is related with the updated section of the guide:

  ```
  // LocaleIndependentAtoi is provided for backwards compatibility reasons.
  //
  // New code should use ToIntegral or the ParseInt* functions
  // which provide parse error feedback.
  //
  // The goal of LocaleIndependentAtoi is to replicate the defined behaviour of
  // std::atoi as it behaves under the "C" locale, and remove some undefined
  // behavior. If the parsed value is bigger than the integer type's maximum
  // value, or smaller than the integer type's minimum value, std::atoi has
  // undefined behavior, while this function returns the maximum or minimum
  // values, respectively.
  ```
